Excel running very slow and causing computer to freeze.

Hi folks,

I am using office 2010 and I have a problem with a  excel spreadsheet running very slow, and i'm looking for ideas on how to fix the problem. I also tried running on office 2013 with the same results.

I have a large spreadsheet freezes anytime I make any type of change. this could take 30 minutes to an hour at times. this happens on all computers I load the file too.

I unchecked automatic calculations and I cleared all formatting, that did not help. Any suggestions would be appreciated.

Something is probably corrupt in the excel file itself, I went through this with a spreadsheet and the only way to track down the issue (if you have multiple pages in the workbook ) is to copy each page to a new blank workbook and test each page's performance there.

What would be the best way to copy each page and making sure all formulas, links and macros are copies too. Thanks for the help.

Even you can try to insert a new sheet in the existing workbook, copy all the data from the problematic sheet by selecting the range with data only (not the whole sheet by pressing Ctrl+A) and paste to newly inserted sheet. You may also copy any code on Sheet Module on the problematic sheet to the newly inserted Sheet Module as well. Now delete that problematic sheet and rename the newly inserted sheet based on your problematic sheet. Repeat these steps if you have more than one sheet originally and save your workbook with a new name and see if the problem resolves.

Also make sure that your formulas on the sheets don't refer to the whole columns or rows.

Sktneer suggestion may be the only way but will take time, first you can try 'file save as' and choose an alternate format which will clear some of the clutter excel like to hang on to and may help the performance. you can always save it back the original format after the fact if needed

If that doesn't work and the move/copy sheets option is the solution the quickest way is to right click each tab and select move/copy - this is faster than cut and paste of individual sheets but may move the corruption as well at which point you will need to follow his suggestion of copying at the data level but I recommend copying into a completely new workbook to be sure of getting rid of the corruption

You can copy the Macros by going into VBA (alt-F11) and exporting all the modules from the sheet then importing them into your new sheet. Make sure to check under the 'workbook' and 'sheets' hierarchy in case any code was stored there too
