How would I delete all rows where the value of a cell "starts with"
something. For example, if I have product numbers like 01-31-030,
01-30-132, 01-30-265 etc... and I want to delete all rows that "start
with" 01-30, how would I do that?

Then, if I want to copy ALL remaining rows/columns to a new
spreadsheet, how would I do that?

I appreciate your help.

Tahrah
