What is NExS?
NExS (Next-generation Excel Spreadsheets) lets you publish Excel workbooks as interactive web applications. If you can build it in Excel, you can deploy it on the web—no coding required.
How it works:
- Build in Excel — Create your calculations using familiar formulas and formatting
- Configure — Add a special
NExS.appworksheet to define your app’s views and inputs - Upload — Upload your
.xlsxfile to the NExS platform - Embed — Get an embed code (script recommended; iframe available) and add it to any web page
Your spreadsheet formulas run on NExS servers, so your business logic stays protected while users interact with a clean web interface.
Who is NExS for?
- Business analysts who want to share calculators without IT involvement
- Energy companies publishing rate calculators for customers
- Finance teams creating interactive pricing tools
- Anyone who builds useful spreadsheets and wants to share them on the web
