[Fixed] Excel Found a Problem with One or more Formula

Summary: The error ‘Excel found a problem with one or more formula references in this worksheet’ may appear while saving the Excel workbook. It occurs when Excel found a problem with the formula used in the sheet. However, it may also occur when the Excel workbook gets damaged or corrupt. In this guide, we’ve explained the reasons that may lead to this Excel error and methods to resolve the error, by using various Excel options and a third-party Excel file repair software.

If you are experiencing the ‘Excel found a problem with one or more formula references in this worksheet’ error message in the Excel workbook, it indicates that the Excel file is corrupt or partially damaged. However, it may also occur due to incorrect reference to a wrong cell or object linking, which is not working. The complete error message says,

‘Excel found a problem with one or more formula references in this worksheet. Check that the cell references, range names, defined names, and links to other workbooks in your formulas are all correct.’

In any case, resolving the error is critical as it doesn’t let you save the file and may result in loss of information from the Excel workbook.

Reasons for Excel Formula References Error

A few reasons that may lead to such error are as follows,

• Wrong formula or reference cell
• Incorrect object linking or link embedding OLE
• Empty or no values in named or range cells
• Multiple Excel files (not common)

Methods to Resolve ‘Excel Found a Problem with One or More Formula References in this Worksheet’ Error

Following are a few methods that you can follow to fix Excel file that can’t be saved due to problems with one or more formula references in the worksheet.

Method 1: Check Formulas

If the problem has occurred in a large Excel workbook with multiple sheets, it’s quite hard to pinpoint the problem cell. In such cases, you can use the Error Checking option that runs a scan and checks for a problem with formulas used in the worksheet.

To run Error Checking in the Excel sheet, follow these steps,

• Go to Formulas and click on the ‘Error Checking’ button

• This runs a scan on the sheet and displays the issues, if any. If no issue is found, it displays the following message,

The error check is completed for the entire sheet.

In such a case, you can try saving the Excel file again. If the error message persists, proceed to the next method.

Method 2: Check Individual Sheet

The problem may also occur due to an issue with one of the sheets in the workbook. To find the faulty sheet and fix the problem, you can copy each sheet content in a new Excel file and then try to save the Excel file.

This will help you find the faulty sheet from the workbook that you can review. This method makes the entire process of troubleshooting Excel formula reference error quite easy and convenient.

In case the error is not fixed, you can back up the faulty sheet content and remove it from the workbook to save the Excel file.

Method 3: Check Links

When the Excel file contains external links with errors, MS Excel may display such error messages. To check and confirm if external links are causing the error, follow these steps,

• Navigate to Data Tab > Queries & Connections > Edit Links
• Check the links. If you find any faulty link, remove it and then save the sheet

Method 4: Review Charts

You can review the charts to check if they are causing the formula reference error in Excel. It may take a while based on the size of the Excel file. Sometimes, it’s not practically possible to track down which Excel chart object is causing the error. Thus, you need to check specific locations, such as:

1. Check horizontal axis formula inside Select Data Source dialog box
2. Check Secondary Axis
3. Check linked Data Labels, Axis Labels, or Chart Title

Method 5: Check Pivot Tables

To check Pivot Tables, follow these steps,

• Navigate to PivotTable Tools > Analyze > Change Data Source > Change Data Source…

• Check if any of the formula used is problematic. Sometimes small typo, such as misplaced comma, can lead to such problems in Excel. Thus, check each formula thoroughly and correct the formulas wherever needed.

Method 6: Use Excel Repair Software

When none of the methods resolve the error, then you can rely on advanced Excel repair software , such as Stellar Repair for Excel. It’s a powerful tool that is recommended by several MVPs and IT administrators for resolving common Excel errors, such as ‘Excel found a problem with one or more formula references in this worksheet.’

It repairs corrupt or damaged Excel (.xls/.xlsx) files, recovers Pivot tables, charts, etc., and save them in a new Excel worksheet. It helps Excel users, facing formula reference error, restore their Excel file without any risk of data loss, while preserving the sheet properties and formatting with 100% precision.

Conclusion

Although the error ‘Excel found a problem with one or more formula references in this worksheet’ can be resolved by using various options in MS Excel, it may lead to a partial loss of information. Thus, you must perform these operations after taking a backup of the Excel worksheet. Also, if the MS Excel options fail to resolve the problem, you can use an Excel file repair software, such as Stellar Repair for Excel. The software helps fix Excel file corruption and restores the information and data from corrupt or damaged Excel files (.xls/.xlsx) to a new worksheet.

How to Fix Excel Formulas Not Working Properly | Step-by-Step Guide

Summary: Excel formulas sometimes fail to function correctly and even return an error. This article explains what you might be doing wrong that prevents Excel formulas from working properly and solutions to resolve the issue. If your formulas have disappeared from the Excel spreadsheet and you are having trouble recovering them, you can use an Excel repair tool to recover the formulas.

When working with Excel formulas, situations may arise when the formula doesn’t calculate or update automatically. Or, you may receive errors by clicking on a formula.

Problems Causing the ‘Excel Formulas not Working Properly’ Issue and Solutions

Let’s check out the possible reasons that cause Excel formulas to work properly and solutions to resolve the issue.

Problem 1 – Switching Automatic to Manual Calculation Mode

Automatic and manual are the two modes of calculation in Microsoft Excel.

By default, Excel is set to automatic calculation mode. Everything is recalculated automatically when any changes are made in a worksheet in this mode. You may switch from automatic to manual mode to disable the recalculation of formulas, particularly when working with a large Excel file with too many formulas.

Excel will not calculate automatically when set to manual calculation mode. And this may make you think that the Excel formula is not working properly.

Solution – Change Calculation Mode from Manual to Automatic

To do so, perform these steps:

• Click on the column with problematic formulas.
• Go to the Formulas tab, click the Calculation Options drop-down, and select Automatic.

Problem 2 – Missing or Mismatched Parentheses

It’s easy to miss or incorrectly place parentheses or include extra parentheses in a complex formula. If a parenthesis is missing or mismatched and you click Enter after entering a formula, Excel displays a message window suggesting to fix the issue (refer to the screenshot below).

Clicking ‘Yes’ might help fix the issue. But Excel might not fix the parentheses properly, as it tends to add the missing parentheses at the end of a formula which won’t always be the case.

Solution – Check for Visual Cues When Typing or Editing a Formula with Parentheses

When typing a formula or editing one, Excel provides visual cues to determine if there’s an issue with the parentheses inserted in a formula. Checking for these visual cues can help you fix missing/mismatched parentheses.

• Excel helps identify parenthesis pairs by highlighting them in different colors. For instance, the pair of parenthesis outside is black.
• Excel does not make the opening parentheses bold. So, if you’ve inserted the last closing parentheses in a formula, you can determine if your parentheses are mismatched.
• Excel helps identify parentheses pairs by highlighting and formatting them with the same color once you cross over them.

Problem 3 – Formatting Cells in an Excel Formula

When adding a number in an Excel formula, don’t add any decimal separator or special characters like $ or €. You may use a comma to separate a function’s argument in an Excel formula or use a currency sign like $ or € as part of cell references. Formatting the numbers may prevent the formula from functioning correctly.

Solution – Use Format Cells Option for Formatting

Use Format Cells instead of using a comma or currency signs for formatting a number in the formula. For instance, rather than entering a value of $10,000 in your formula, insert 10000, and click the ‘Ctrl+1’ keys together to open the Format Cells dialog box.

Problem 4 – Formatting Numbers as Text

Numbers are displayed as left-aligned in a sheet in a worksheet, and text formatted numbers are right-aligned in cells. Excel considers numbers formatted as text to be text strings. Thus, it leaves those numbers out of calculations. As a result, a formula won’t work as intended. For example, in the following screenshot, you can see that the SUM formula works correctly for normal numbers. But, when the SUM formula is applied to numbers formatted as text, the formula doesn’t return the correct value.

Sometimes, you may also see an apostrophe in the cells or green triangles in the top-left corner of all the cells when numbers in those cells are formatted as Text.

Solution – Do Not Format Numbers as Text

To fix the issue, do the following:

• Select the cells with numbers stored as text, right-click on them, and click Format Cells.
• From the Format Cells window, click on Number and then press OK.

Problem 5 – Double Quotes to Enclose Numbers

Avoid enclosing numbers in a formula in double-quotes, as the numbers are interpreted as a string value.

Meaning if you enter a formula like =IF(A1>B1, “1”), Excel will consider the output one as a string and not a number. So, you won’t be able to use 1’s in calculations.

Solution – Don’t Enclose Numbers in Double Quotes

Remove any double quotes around a number in your formula unless you want that number to be treated as text. For example, you can write the formula mentioned above as “1” =IF(A1>B1, 1).

Problem 6 – Extra Space at Beginning of the Formula

When entering a formula, you may end up adding an extra space before the equal (=) sign. You may also add an apostrophe (‘) in the formula at times. As a result, the calculation won’t be performed and may return an error. This usually happens when you use a formula copied from the web.

Solution – Remove Extra Space from the Formula

The fix to this issue is pretty simple. You need to look for extra space before the equal sign and remove it. Also, ensure there is an additional apostrophe added in the formula.

Other Things to Consider to Fix the ‘Excel Formulas not Working Properly’ Issue

• If your Excel formula is not showing the result as intended, see this blog .
• When you refer to other worksheets with spaces or any non-alphabetical character in their names, enclose the names in ‘single quotation marks’. For example, an external 5reference to cell A2 in a sheet named Data enclose the name in single quotes: ‘Data’!A1.
• You may see the formula instead of the result if you have accidentally clicked the ‘Show Formulas’ option. So, click on the problematic cell, click on the Formula tab, and then click Show Formulas.
• If you’re getting an error “Excel found a problem with one or more formula references in this worksheet”, find solutions to fix the error here .

Conclusion

This blog discussed some problems you might make causing an Excel formula to stop working properly. Read about these common problems and solutions to fix them. If a problem doesn’t apply in your case, move to the next one. If you cannot retrieve formulas in your Excel sheet, using an Excel file repair tool like Stellar Repair for Excel can help you restore all the formulas. It does so by repairing the Excel file (XLS/XLSX) and recovering all the components, including formulas.

How to fix runtime error 424 object required error in Excel

The Runtime error 424: Object required occurs when Excel is not able to recognize an object that you are referring to in a VBA code. The object can be a workbook, worksheet, range, variable, class, macro, etc. Some users have also reported that this error occurred when they tried to copy the values of the cells from one workbook to another.

Let’s understand the error through a small scenario. Suppose, I want to check the last field row in a table in a spreadsheet named “First” using the VBA code. To do this, I have added a command button and double-clicked on it and entered the below code in the backend:

Private Sub CommandButton2_Click()

Dim LRow As Integer

LRow = Worksheets(“First”).Cells(Rows.Count, 2).End(xlUp).Row

MsgBox (“Last Row “ & LRow)

End Sub

In this code, Worksheets(“First”) is a data object. If I mistakenly delete this data object and insert any random name (for example - kanada), then it will not be recognized by Excel. When I run this code, I will get the “Run-time error 424”.

Causes of Runtime Error 424 in Excel

The Runtime error 424: Object required can occur due to the following reasons:

• Incorrect name of the object you are trying to refer to in a code.
• You have provided an invalid qualifier to an object.
• You have not used the Set statement while assigning an object reference.
• The object is corrupted.
• Missing objects in a workbook.
• Objects you are trying to call in a code are mistakenly deleted or unavailable.
• You have used an incorrect syntax for object declaration.
• You are trying to perform an invalid action on an object in a code.

The VBA error ‘object required’ may occur due to different reasons. Based on the reason, you can follow the solutions mentioned below to fix the error.

1. Check the Name of the Object

The Runtime error 424 can occur when you run the VBA code using an incorrect name of the object. For example, the object name is ‘MyObject’ but you’re using “Backcolor”.

 When you click the Debug button, the line with the error will highlight.

To fix the issue, you need to provide the correct name of the object.

2. Check if the Object is Missing

 The Runtime error 424 can occur if the object you are referring to as a method is not available or you are using the wrong object in a code. In the below example, you can see that the error occurs when an object named “Employee” is not available in the Project list.

 You can check and mention the object which is available. For instance, Sheet2 in the below code.

3. Check All References are Declared in the Code

You can get the Runtime error 424 if all the references are not declared. So, make sure you have declared all the references in the code. To verify this, you can use the debug mode by pressing F5 or clicking on the Debug option.

4. Check the Macro Security Settings

Sometimes, the error can occur if macros are disabled in the Macro Security settings. You can check and change the settings by following these steps:

• On the Developer tab, in the Code section, click Macro Security.
• In the Trust Center window, select Enable all macros.

• Click OK.
