Steps to Repairing Microsoft Excel Errors for Your Computer


What Is a Windows Microsoft Excel Error?

If you’re attempting to open a Microsoft Excel file and the file won’t open, you may receive a Microsoft Excel Error. The error might read: There was a problem sending the command to the program; or An error occurred in sending the command to the application. This error can still occur when the Excel application opens without an issue, but the Excel file you’re attempting to open will not.


What Causes a Windows Microsoft Excel Error?

A Microsoft Excel Error can occur when an Excel setting is set to not allow certain files from opening when the file comes from a Dynamic Data Exchange (DDE). This setting is often enabled as the default setting. A Microsoft Excel Error could also occur when the file type is not recognized by your computer or the file is corrupt.


How to Fix a Windows Microsoft Excel Error

There are a couple options to choose from when attempting to fix a Microsoft Excel Error of this type, depending on the root of the issue.

Solution 1: Check the file extension to confirm its .xls.


  1. Confirm you have Microsoft Excel software installed on your computer. If you do, proceed to Step 2. If you don’t, download the software to resolve the issue and you can most likely stop here.
  2. Confirm the file extension for the file you’re attempting to open is .xls.
  3. If the file extension is .xls, proceed to Solution 2 below. If it’s not .xls, proceed with this solution.
  4. Locate the file you’re attempting to open.
  5. Right click on the file.
  6. Select Save As.
  7. When the Save As box opens, under Save as File Type, select Excel Workbook from the drop down list.
  8. Click Save.
  9. Try to reopen the file.
  10. If it still doesn’t work, repeat Steps 4 through 6 above.
  11. When the Save as box opens, save the file to your hard drive without making any changes.
  12. Right click on the file.
  13. Select Rename.
  14. Change the extension to .xls.
  15. Try reopening the file.


Solution 2: Disable the Setting that Prevents files from opening that come via DDE

  1. Open Microsoft Excel.
  2. Click on the Office logo button in the upper left hand corner of the program. Note: If you’re using Microsoft Office 2010, the Microsoft Office button is no longer present. Instead, there’s what’s called a Backstage which is the Microsoft Excel X in the upper left hand corner.
  3. Select Excel Options.
  4. Click on Advanced.
  5. Scroll down to General.
  6. Uncheck the box beside Ignore other applications that use Dynamic Data Exchange (DDE).
  7. Click on OK.
  8. Click Apply.
  9. Try to reopen the Excel file that you originally prompted the Microsoft Excel Error.
