Our online spreadsheet editor gives you the power of a desktop spreadsheet application directly in your browser. Create, edit, and format spreadsheets without installing Excel or any other software. It supports formulas, cell formatting, multiple sheets, and all the core features you need for data analysis, budgeting, and reporting.
You can import existing Excel files in .xlsx or .xls format and open CSV files as well. Once loaded, edit your data freely and export back to .xlsx or download as CSV for use in other tools. The editor handles large datasets efficiently and supports standard spreadsheet functions including SUM, AVERAGE, IF, VLOOKUP, and many more.
The spreadsheet engine is built on the powerful Univer framework, which delivers near-native performance for complex operations. It runs entirely in your browser — no server-side processing means your data stays completely private. There is no need to upload sensitive financial or business data to a third-party server.
Use the online spreadsheet for expense tracking, project management, data cleaning, financial modeling, or any task that benefits from a structured grid layout. It works seamlessly on Windows, macOS, and Linux, and supports all modern browsers without plugins or extensions.
Whether you're a student, freelancer, or business professional, our free online spreadsheet tool saves you time and removes the need for expensive software subscriptions. Open it any time from any device and get straight to work.
