Does this tool execute JavaScript to evaluate formulas?

No, it uses a bounded parser to evaluate Excel-style formulas safely without executing arbitrary JavaScript.

Can I reference other formulas in my cell values?

Yes, you can define formulas as string values in your JSON cells, and the evaluator will resolve the dependency chain.

What types of spreadsheet errors does the evaluator detect?

It reports standard spreadsheet diagnostics including invalid references, division by zero, and circular dependencies.

How do I format the cell values input?

Provide a valid JSON object where keys are cell coordinates (e.g., "A1", "B2") and values are numbers, strings, or nested formulas.

Which Excel functions are supported?

It supports common arithmetic operators, cell/range references, aggregation functions like SUM and AVERAGE, and conditional functions like IF.
