Date Inconsistency Is a Small Problem That Creates Big Noise
A single column showing 2026/4/1, 2026-04-01, and April 1 side by side doesn't just look sloppy — it signals inconsistent data entry to anyone reading it.
Ctrl+Shift+3 is the standard shortcut for locking in date formatting. It also serves as a quick diagnostic: if the format doesn't apply, the cell may not contain a true date value.
How to Standardize Date Formatting
Date columns are most efficiently formatted in one pass — either right after entry or just before submission.

Things to Watch Out For With Date Formatting
Changing the display format doesn't fix text-string dates — sorting and calculations will still fail if the values aren't true dates.
Standardizing input rules is more effective than cleaning up formatting after the fact.
For external reports, confirm whether year-month-day or full date with year is required.
