David Pharmacy 777 -

I have run oput of columns on my sheet. I can't insert any more. Can I
increase this limitation? <

The limit is 256 columns, and it cannot be changed.

If you're not using all 256, and if you cannot insert a column, there may be
some columns on the far right that seem to be empty but that Excel thinks
contain data or that previously contained data. If you select those columns
on the far right and delete (or clear contents), you may be able to insert
columns again.
