How it works.
OR evaluates multiple conditions and returns TRUE if at least one condition is met. It returns FALSE only if all conditions are FALSE. It is commonly used inside IF statements to check alternative conditions.
💡 In simple terms.
Checks multiple rules. It outputs TRUE if at least one rule is met; it only outputs FALSE if all rules fail.
"Think of this like qualifying for a free drink. You qualify IF you have a coupon OR it is your birthday. You only need one of them to be true!"

Best Practices
- Use OR to check if a cell contains one of several options: e.g. `=OR(A2="Red", A2="Green", A2="Blue")`.
Common Mistakes
- If you supply array ranges to OR, they must be formatted correctly, otherwise it can return #VALUE! or slow down calculation.

Frequently asked questions.
Technical Q&ACan I use OR across different worksheets in Excel?↓
Yes. You can reference cells located on other sheets by including the sheet name followed by an exclamation mark, for example: =OR(Sheet2!A2:A10). If the sheet name contains spaces, enclose it in single quotes: ='Q1 Report'!A2:A10.
What is the most common reason for errors in OR?↓
If you supply array ranges to OR, they must be formatted correctly, otherwise it can return #VALUE! or slow down calculation.
Does OR work identically in Google Sheets?↓
Yes, OR is supported in both Microsoft Excel and Google Sheets with standard evaluation behavior.
