Nia Sheets is a free, modern spreadsheet application built for data professionals who need more than Excel. At its core is Nia Agent — an AI data analyst that lives inside your spreadsheet. Describe what you want in plain English: chart this data, find anomalies, generate a formula, summarise the trend — and Nia does it instantly.
Connect live to PostgreSQL, MySQL, SQLite, or SQL Server and query your database directly from your spreadsheet. Data stays in sync. No exports, no copy-paste. Combine database tables with local data in a single sheet using familiar spreadsheet formulas.
Nia Sheets supports 500+ Excel-compatible functions, so your existing formulas work without modification. Pivot tables, conditional formatting, sparklines, data bars, and 20+ advanced chart types give you complete analytical power. For enterprise teams, the built-in CPM (Corporate Performance Management) module adds budgeting, forecasting, variance analysis, and automated dashboard reporting with scheduled email delivery.
Available on Web, macOS, Windows, and Linux. Completely free during early access — no credit card required.

Customer reviews
Nia Sheets replaced our entire Excel workflow in a week. The AI formula assistant is genuinely magical — I described a complex VLOOKUP in plain English and it just worked.
The live database connection is a game-changer. I query our Postgres DB directly from the spreadsheet. No more CSV exports.
Best free Excel alternative I've found. The pivot tables handle our 800K-row datasets without any lag. Genuinely impressive.
