Key notes

  • When users try to open an Excel spreadsheet or import a CSV file, they get an error that the Microsoft Excel file is not fully loaded.
  • A possible solution is to use alternate software to open the file that is too big for Excel.

The Microsoft Excel File not loaded completely error arises when users try to open an Excel spreadsheet or import a CSV file so big that is not supported by Excel. When that error arises, the File not loaded completely dialog box opens which explains why the error message appears. That dialog box states:

This message can appear due to one of the following : The file contains more than 1,048,576 rows or 16,384 columns… The area that you are trying to paste the tab-delineated data into is too small.

That error often arises when users try to open spreadsheets that eclipse Excel’s maximum worksheet limit specifications for total columns and rows.

Alternatively, you might try to import CSV data into a sheet that eclipses Excel’s maximum limit specs. The Excel specifications and limits page provide full details for all the application’s maximum limits.

How do I fix the File not loaded completely error?

1. Open the spreadsheet with alternative software

Most spreadsheet applications support Excel’s file format. So, try opening the Excel file in an alternative freeware spreadsheet application that might not have the same maximum limits.

If you can open it in alternative spreadsheet software, you can reduce the number of rows and columns in the file so that it opens in Excel.

Alternatively, try opening the spreadsheet with a universal file opener (UFO) software. File Viewer Lite is a freeware UFO software you can add to Windows by clicking Free Download on its page. After installing it, open the Excel spreadsheet in File Viewer Lite.

Note, however, that you can only save modified spreadsheets with File Viewer Plus, which is the full version.
