Practical guides and ideas for turning Microsoft Excel spreadsheets into REST APIs, automated workflows and monetizable web services — without writing code. We cover how Businesslogic works in practice: publishing an Excel model as an API, wiring it into the tools your team already uses, building live calculators and configurators, and turning hard-won spreadsheet expertise into a product. Whether you are a business owner who lives in Excel or a developer who needs a clean JSON contract, you will find step-by-step walkthroughs and real examples here.

What you'll find here
These articles are written for people doing the work, not skimming theory. Most are step-by-step: open a spreadsheet, follow along, end up with something that runs. Three threads run through them:
- Publishing Excel as an API — taking a workbook from file to documented JSON endpoint, and what to mark as inputs and outputs.
- Connecting it to your stack — using your model inside Make (Integromat), Zapier and other tools, plus live calculators and configurators on your own site.
- Turning expertise into a product — pricing, scoring and engineering logic you can sell per call instead of per hour.
