Sheet1, Sheet2 gets confusing fast
In a workbook with several sheets, leaving them with default names quickly becomes confusing about what's stored where. Giving each sheet a clear name lets you find what you're looking for much faster.
Consider tab colors too
It's also worth exploring how to color-code and hide sheet tabs, since that pairs well with clear naming to organize a workbook with many sheets at a glance.
Frequently Asked Questions
Are there characters I can't use in a sheet name?
Yes. Certain special characters β including the slash (/), question mark (?), asterisk (*), and colon (:) β can't be used in a sheet name.
Do formulas update automatically if I rename a sheet?
Yes. If any formulas reference the sheet, Excel automatically updates those references to match the new name when you rename it.
