True, i was mostly wondering if there was a color i could use for when i added new changes, so they would be easily seen. But i guess i just have to add a searchable key word in a comment then. Thanks for the help though!
The Track Changes Option in Excel will show all changes made and highlight them on the sheet, if by code you mean VBA macro code then no!
Turn on change tracking for a workbook
On the Tools menu, click Share Workbook, and then click the Editing tab.<LI class=LPROC>Select the Allow changes by more than one user at the same time check box. <LI class=LPROC>Click the Advanced tab. <LI class=LPROC>Under Track changes, click Keep change history for, and in the Days box, type the number of days of the change history that you want to keep. Be sure to enter a large-enough number of days because Microsoft Excel permanently erases any change history older than this number of days.
Click OK, and if prompted to save the file, click OK.
Note Turning on change tracking also shares the workbook. </INPUT>
