Read the formula you did not write
Paste a spreadsheet formula and SheetDecode breaks it into the order it runs in, names what each argument is for, warns about the mistakes that formula shape is prone to, and diagnoses the red error values.
Yes. Formulas are parsed on your device; nothing is uploaded.
No. Formulas you decode stay in memory on your device for the length of your session. We do not save them, sync them, or send them anywhere, and there is no account or sign-in.
Around fifty of the most common ones. A formula containing a function outside that set still gets its structure explained, and the unknown name is flagged — which is usually the cause of #NAME?.
#REF!, #VALUE!, #N/A, #DIV/0!, #NAME?, #NUM!, #NULL! and #SPILL!.
Some warnings are about mistakes that produce a wrong answer rather than an error — an approximate-match lookup, for instance. They are worth reading even when the sheet looks fine.
