Can use VSTO to reduce the size of a file?

[LuisE]

I have a really large spreadsheet that is saved in a sharepoint location but
takes about five minutes to load.

Would it make any difference if I recreate the file using VSTO?

Thanks in advance

Recreating the file might help, particularly if large areas include
unnecessary formatting. However what means you use to do that, manually,
VBA, VSTO etc, wouldn't be directly relevant.
