Start
Formulon is a headless spreadsheet calculation engine. Choose where it will run, verify the installation with a small formula, then test a representative workbook.
New to spreadsheet engines?
Basic concepts explains the three products, cell coordinates, and the difference between formulas, calculated values, and display text. Use the glossary when a guide introduces an unfamiliar term.
Recommended path
Prove the install with one formula, then prove the fit with a real workbook, before building a use case on it.
- Choose a surface and install its package.
- Run one formula through Formulon.
- Recalculate one workbook.
- If the result differs from Excel, check Formula coverage, File format support, and Error model.
- Move to a concrete Use case.
