Power Fx Formula Checker
Paste a Power Fx formula to catch common mistakes before you paste it into Power Apps Studio: unbalanced brackets, curly quotes, == instead of =, wrongly cased function names, unknown functions and the wrong number of arguments. Each issue shows its line and column.
Also known as: power fx validator, power apps formula checker, power fx syntax checker, power apps formula error, check power fx online.
This checker looks at brackets, quotes, operators, function names and argument counts. It cannot see your controls, column names, data types or delegation limits, so Power Apps Studio remains the final check.

Does this replace Power Apps Studio?
No. It checks structure and function usage only. Studio also knows your controls, columns, data types and delegation limits.
Why is a function marked as unknown?
It may be misspelled, or it may be a connector action, a flow or a custom function, which this checker cannot see. Unknown names are shown as warnings for that reason.
