Purchase \Lambda Library 2025 as an Excel worksheet
- You can support \Lambda by purchasing a workbook containing all the Lambda functions listed on the site.
- The price is $15 (taxes apply). This price will never change. No good or bad deals here, just pure Excel goodness.
- You get free updates (all bug fixes and functions that we add to the library) until the end of 2026.
- The worksheet includes all the functions and documentation available for free on the BackslashLamda.com website. What you are paying for is convenience – transferring a Named Lambda from the library to your own workbook is as easy as copy/pasting a cell.
- You are also supporting the efforts of the BackslashLambda one-man team 🙂
- Make sure to check the free preview before purchase, so you know what to expect.
