Maybe you can delete smaller chunks of rows and columns and do it multiple
times.

Debra Dalgleish once asked a user who complained about the size of a workbook
growing too fast:

Do you copy from the web and paste into your workbook. (Paraphrased).

Her thought was that maybe you were copying shapes/pictures/objects and pasting
them, too.

My relatively small shared workbook seems to have grown to 11MG overnight. I
have tried to delete the unused rows and columns but keep getting an error
about too much data. Is there anyway to set the last row/column or cell
without deleting these?
