If you have ever created a workbook in Microsoft Excel that was too large for memory, you know how frustrating it can be. The workbook may take a long time to load, or you may get an error message saying that the file is too big. There are a few things that you can do to try to fix this problem.
First, try to reduce the size of the file by deleting unnecessary data. If the file is very large, you may need to delete entire sheets of data. You can also try to compress the file by going to File > Save As and selecting the "Zip" option under the "Save as type" drop-down menu. This will create a compressed version of the file that may be small enough to open in Excel.
If neither of these options works, you can try opening the file in another program such as OpenOffice Calc or Google Sheets. These programs often have no problem opening very large files that Excel cannot handle. Once you have opened the file in another program, you can save it as a new file and then open it in Excel.
Finally, if none of these options work, you may need to split the large file into smaller files. You can do this by going to File > Save As and selecting the "CSV (Comma delimited)" option under the "Save as type" drop-down menu. This will save the file as a CSV file which can be easily split into multiple smaller files using a free online tool such as SplitCSV. Once you have split the CSV file into smaller files, you can open each one in Excel.
