A formula that stops too early
Parse errorThe file could not be read. Nothing is converted until the line is corrected.
What the converter says
the formula stops before its )
What triggers it
The formula ends before something it needs: a closing bracket, the value after an operator, or the ELSE half of a condition.
XA="(L/2"How to fix it
Finish the formula. Every IF needs a THEN and an ELSE, and every opening bracket needs a closing one.
