Excel Stuck at Opening File 0% - Resolve Performance Issues

Summary: If an Excel workbook is stuck at opening file 0%, it usually indicates a problem with the Excel file and its objects. This may happen due to Excel file corruption and a few other reasons. In this post, we have discussed these reasons along with the methods to fix and prevent ‘Excel stuck at opening file 0%’ issue.

When you open an Excel file (XLS/XLSX) in MS Excel, the program reads and then loads the file data along with all its objects and properties. While opening and loading an Excel file, MS Excel displays an “Opening percentage.” You won’t usually notice or see this Excel file opening progress percentage while accessing smaller worksheets.

It’s more noticeable when you open a large Excel file or workbook with multiple objects, formulae, formatting, etc. However, after opening an Excel file with double-click, if it is stuck at Splash Screen with a message “Opening: FileName.xlsx (0%)” for a while (say 15-30 minutes) and does not progress, it indicates a problem with the Excel file, MS Excel program, or the system.  

Why Excel is Stuck at Opening File 0%?

If you have encountered this error, it may happen due to one of the following issues,

1. Damaged or corrupt Excel file
2. Incompatible or faulty Excel add-ins
3. Problem with the system’s display driver
4. Damaged MS Office (Excel) application

Methods to Fix ‘Excel Stuck at Opening File 0%’ Issue

Before fixing and troubleshooting the problem, check and confirm if the Excel file is working and not corrupt. For this, you can try opening it on another PC. Now there could be two scenarios,

Scenario 1:  Excel File Does Not Open

If the Excel file doesn’t open on another PC also, it indicates Excel file corruption. In such cases, look for the backup copy of the file, if you have downloaded it from an email or a website.

However, if there’s no backup, then you need an Excel file repair software, such as Stellar Repair for Excel to repair the corrupt file. This software preserves Excel file properties, such as cell formatting, formula bar, freeze panes, gridlines, etc. and helps you restore the damaged or corrupt worksheets to its original state with 100% integrity.

To repair Excel file, download and launch Stellar Repair for Excel software on your PC, choose the corrupt Excel (XLS/XLSX) file and click ‘Repair’. You can see the preview of your Excel file with all data and then save the repaired file at your desired location on the system as a new Excel file.

Scenario 2: Excel File Is Accessible on Another PC

If the Excel file opens successfully on another PC, then follow the troubleshooting methods below to resolve the Excel file stuck opening at 0%.

Method 1: Open MS Excel in Safe Mode

To check if an incompatible or faulty add-in or setting is causing the error, restart MS Excel in safe mode and then open the worksheet from the MS Excel ‘File’ options. The steps are as follows,

1. Press Windows+R and type excel.exe /safe
2. Hit Enter or press ‘OK’ to open MS Excel in safe mode

• Go to File > Open and then choose the Excel file to open it
• If it opens, the problem is probably caused by the add-ins. Go to File > Options > Add-ins > Manage > COM Add-ins and disable all the third-party add-ins

• Restart MS Excel normally and then go to File > Open and open the same Excel file. If it opens, the problem is solved.

However, if you want to keep the add-ins, enable one add-in at a time and open the same file to find which add-in is causing the problem. When found, remove the faulty add-in.

If it doesn’t work, head to the next solution.

Method 2. Disable Hardware Graphics Acceleration

If you’re using hardware graphics acceleration adapter to run an external monitor, you may encounter problems with the Excel application. If the adapter is plugged in but doesn’t work correctly, Excel will usually hang on the loading screen. To resolve this problem, you will need to disable the hardware graphics acceleration adapter by following these steps,

• Quit all running instances of Excel from Task Manager

• Launch MS Excel directly, don’t double-click on the faulty workbook file to open MS Excel as it won’t open
• Click on File > Options > Advanced

• Under the ‘Display’ options, check the box ‘Disable hardware graphics acceleration’
• Click on ‘OK’

Try to open the Excel file now. If it still doesn’t work, move to the next solution.

Method 3. Repair MS Excel Application and Install the Latest Updates

Problems within MS Excel installation could also be a source of many unknown issues. Messed up registry settings, bugged updates, and even wrong user ‘Preferences’ can cause your Excel application to behave unusually. The fix for all such issues is to repair the Excel installation. To do so, follow these steps,

• Open Control Panel
• From Category view, under Programs, select Uninstall a program
• Click on the MS Office and then click ‘Change’

• When prompted, click on ‘Repair’ and then follow the instructions to complete the repair process

To update the MS Excel,

• Go to File > Account and click on Update options

• Then click ‘Update’

• MS Excel will start downloading the latest updates and then apply it, which might fix this Excel error

Still, Excel stuck on processing file at 0%? That means the Excel file you’re trying to open is severely corrupted.

[Fix] Excel formula not showing result

Summary: Is your Excel spreadsheet showing text of a formula you’ve entered and not its result? This blog explains the possible reasons behind such an issue. Also, it describes solutions to fix the ‘Excel formula not showing result’ error. You can try Stellar Repair for Excel software to recover engineering and shared formulas.

Sometimes, when you type a formula in a cell of worksheet and press Enter, instead of showing the calculated result, it returns the formula as text. For instance, Excel cell shows:

But you should get the result as:

Why Does Excel Show or Display the Formula Not the Result?

Following are the possible reasons that may lead to the ‘Excel showing formula not result’ issue:

1. You accidentally enabled “Show Formulas” in Excel.
2. The cell format in a spreadsheet is set to text.
3. ‘Automatic calculation’ feature in Excel is set to manual.
4. Excel thinks your formula is text (Syntax are not followed).
5. You type numbers in a cell with unnecessary formatting.

How to Fix ‘Excel Showing Formula Not Result’ Issue?

Solution 1 – Disable Show Formulas

If only the formula shows in Excel not result, check if you have accidentally or intentionally enabled ‘show formula’ feature of Excel. Instead of applying calculations and then showing results, this feature displays the actual text written by you.

You can use the ‘Show Formulas’ feature to quickly view all formulas, but if you are not aware of this feature, and enabled it accidentally, it can be a headache. To disable this mode, go to ‘Formulas’ and click on ‘Show formula enabled.’ If it’s previously enabled, it will be disabled by just clicking on it.

Solution 2 – Cell Format Set to Text

Another possible reason that only formula shows in Excel not result could be that the cell format is set to text. This means that anything written in any format in that cell will be treated as regular text. If so, change the format to General or any other. To get Excel to recognize the change in the format, you may need to enter cell edit mode by clicking into the formula bar or just press F2.

Solution 3 – Change Calculation Options from ‘Manual’ to ‘Automatic’

There is an “automatic calculation” feature in Excel, which tells Excel to do calculations automatically or manually. If ‘Excel formula is not showing results’, it may be because the automatic calculations feature is set to manual. This issue is not easily detected because it results in calculating formula in one cell but if you copy it to some other cell, it will retain the first calculation and will not recalculate on the base of the new location. To fix this, follow these steps:

• In Excel, click on the ‘File’ tab on the top left corner of the screen.
• In the window that opens, click on ‘Options’ from the left menu bar.
• From ‘Excel Options’ dialog box, select ‘Formulas’ from the left side menu and then change the ‘Calculation options’ to ‘Automatic’ if it’s currently set as ‘Manual’.

• Click on ‘OK’. This will redirect you to your sheet.

Solution 4 – Type Formula in the Right Format

There is a proper way to tell Excel that your text is a formula. If you don’t write the formula in a particular format, Excel considers it as simple text and hence no calculations are performed according to it. For this reason, keep the following in mind when typing a formula:

• Equal sign: Every formula in Excel should start with an equal sign (=). If you miss it, Excel will mistake your formula as regular text.

• Space before equal sign: You are not supposed to enter any space before equal sign. Maybe a single space will be hard for us to detect, but it breaks the rule of writing formulas for Excel.

• Formula wrapped in quotes: You need to make sure that your formula is not wrapped in quotes. People usually make this mistake of writing a formula in quotes, but in Excel, quotes are used to signify text. So your formula won’t be evaluated. But you can add quotes inside formula if required, for example: =SUMIFS(F5:F9,G5:G9,”>30″).

• Match all parentheses in a formula: Arguments of Excel functions are entered in parenthesis. In complex cases, you may need to enter more sets of parenthesis. If those parentheses are not paired/closed properly, Excel may not be able to evaluate the entered formula.

• Nesting limit: If you are nesting two or more Excel functions into each other, for example using nested IF loop, remember the following rules:

  • Excel 2019, 2016, 2013, 2010, and 2007 versions only allow to use up to 64 nested functions.
  • Excel 2003 and lower versions only allow up to 7 nested functions.

Solution 5 – Enter Numbers without any Formatting

When you use a number in the formula, make sure you don’t enter any decimal separator or currency sign, e.g. $, etc. In an Excel formula, a comma is used to separate arguments of a function and a dollar sign makes an absolute cell reference. Most of these special characters have built-in functions so avoid using them unnecessarily.

What to Do If the Manual Solutions Don’t Work?

If you’ve tried out the manual solutions mentioned above but still unable to resolve the ‘Excel formula not showing result’ issue, you can try repairing your Excel file with the help of an automated Excel repair software , such as Stellar Repair for Excel.

This reliable and competent software scans and repairs Excel files (.XLSX and .XLS). It also helps recover all the file components, like formulas, cell formatting, etc. Armed with an interactive GUI, this software is extremely easy to work with, and its advanced algorithms allow it to fend off Excel errors with ease.

Conclusion

This blog outlined the possible reasons that may cause ‘Excel not showing formula results’ issue. Check out these reasons and implement the manual fixes, depending on what resulted in the problem in the first place. If none of these fixes help resolve the issue, corruption in the Excel file might be preventing the formulas from showing the actual results. In that case, using Stellar Repair for Excel tool might help.
