Spreadsheet Software — Evolved
Excel and Google Sheets are great for building models. But they weren't built for sharing, app creation, or automation. Airrange extends your spreadsheet software — turning Excel workbooks into web apps, calculators, APIs, and secure sharing tools. Your formulas stay intact.
What Is Spreadsheet Software?
Spreadsheet software is any program that organizes data in rows and columns, with support for formulas, charts, and data analysis. The most popular spreadsheet programs are Microsoft Excel and Google Sheets, followed by LibreOffice Calc, Apple Numbers, and Zoho Sheet.
These tools are incredibly versatile — from simple lists to complex financial models with thousands of formulas. But they share common limitations when it comes to collaboration, sharing, and turning models into usable tools for others.
Airrange is not a spreadsheet replacement. It's a layer on top that extends what your spreadsheet software can do — turning your existing workbooks into apps, APIs, and secure sharing solutions.

Frequently Asked Questions
What is the best spreadsheet software?
For editing spreadsheets, Microsoft Excel is the most powerful (especially for formulas), and Google Sheets is the best free option. For turning spreadsheets into apps and sharing tools, Airrange extends what Excel can do without replacing it.
Is there free spreadsheet software?
Google Sheets is free. LibreOffice Calc is a free, open-source desktop alternative. Airrange offers a free plan for building apps from your spreadsheets — up to 25 elements.
Can spreadsheet software build apps?
Traditional spreadsheet software (Excel, Sheets) can't build apps natively. Google offers AppSheet as an add-on, but it requires rewriting formulas. Airrange works directly with your Excel formulas to create web apps — no rewriting needed.
Is Airrange a spreadsheet program?
No. Airrange is not a spreadsheet editor. It's a platform that extends your existing spreadsheet software — turning Excel workbooks into web apps, calculators, APIs, and granular sharing tools. You keep using Excel for modeling.
Does Airrange work with Google Sheets?
Airrange is built for Excel. It works with local .xlsx files and Microsoft 365 workbooks. For Google Sheets-based tools, AppSheet or Glide are alternatives.
How much does Airrange cost?
Free plan with 25 elements. Paid plans from €19/month (Lite) and €49/month (Pro) with granular sharing and data entry. See pricing →
