I use Excel to post client account records, some of which are many screens long. Every time I reopen Excel to make a new entry on a worksheet, it has defaulted to the top and I need to scroll down to the point to make a new entry manually. Doing a Ctrl-End sends me to the absolute bottom of the file's potential limit. Is there a way to change this default to simply leave the worksheet at the point it was saved?

If I am working at row 456, save the file and close it and after that open it, it will open there where I was when I saved it, in this case Row 456.
It doesn't do that for you?

Can it be that your workbook contains a Workbook Open macro that sets Excel open at the top?

No. I have about a dozen client columns and they all revert to top-of-page, regardless of the fact that I saved the entire file with each column left where I left off.

I converted, or I should say Excel automatically converted, these files from Apache Open Office, but I never had the issue there and I haven't created any macros or done anything w/ Excel 2016 on-line since I began using it a few months ago.
