I was given a large spreadsheet (737 rows and 45 columns) to clean up before
transferring into a database file. Certain cells text, others numbers,
emails, etc. and some are color coded to identify a specific distribution
process.

Whenever I try to sort the data, the following message shows up and it won't
allow me to sort. "The operation requires the merged cells to be identically
sized"

I have spent the better part of a day trying to find the merged cells, but
have failed. Is there some way to find merged cells with the sheet without
clicking on every cell individually? Is there some other way to accomplish
the task for sorting? Thank you.
