Trying to find out how to unhide rows/columns. I've tried to use Format/Row/Unhide but it doesn't work. Also, is there a way to start at one row and highlight to the very bottom 66000+ rows. Any help would be very appreciated.
If you can't delete a row by clicking on the column displaying the row number to select the row, then right-clicking, and selecting delete row, then the workbook you're working with is protected against deleteing rows.
When you use Format > Row > Unhide do you have the rows above and below the
hidden row(s) selected?
To highlight from one row to any number of rows below that you simply need to select
a cell in the starting row (or the row number at the left to include the
entire row) and scroll down to the last desired row and hold the Shift button while
selecting the cell (or row number) for the last row.
Also, unless you're using the newest version of Excel you don't have 66,000 +
rows to work with. You'll only have 65,536 rows at best.
If I've misunderstood what you're looking to do then post back with more details.
