What is date format in Google Sheets?
Date Format is how Google Sheets stores or interprets values in cells: numbers, text, dates, booleans, and locale-specific separators. Format and locale settings change what you see without always changing the stored value.
When to use it
Use format and type knowledge when imports look like text, dates shift by a day, or decimals use the wrong separator.
When to skip it
Skip custom format rabbit holes when plain number or date formats already display correctly for your audience.

cell formatting
Cell formatting controls how values display without necessarily changing the stored value underneath. Currency, percent, date, and plain text formats keep reports readable and prevent Sheets from auto-converting IDs into dates. Good formatting is the difference between a sheet leadership trusts and one they argue with.
Read guide →Locale separators
Locale controls whether function arguments separate with commas or semicolons and whether decimals use dot or comma. A sheet set to France may expect =SUM(A1;A10) while US expects =SUM(A1,A10). CSV imports and array literals also clash when decimal commas meet comma separators. File > Settings > Locale sets the default behavior for new formulas in that file.
Read guide →Data validation
Data validation restricts what can be entered in a cell before bad data spreads through your model. Rules can enforce dropdown lists, number ranges, dates, text length, or custom formulas that return TRUE. Invalid entries can be rejected or warned with a note. Validation is the front door quality check for shared trackers and intake sheets.
