How to Import Your CSV into Google Sheets
Why Convert Excel to Google Sheets?
Microsoft Excel and Google Sheets are the two most widely used spreadsheet tools in the world, but they serve different workflows. Excel excels at complex calculations, financial modeling, and working with very large datasets on your desktop. Google Sheets is built for real-time collaboration, cloud access, and sharing data across teams without worrying about file versions.
The most common reason people convert Excel files to Google Sheets is collaboration. When a team needs to work on the same spreadsheet simultaneously — editing cells, leaving comments, and seeing changes in real time — Google Sheets is the better tool. Rather than emailing Excel files back and forth and dealing with conflicting versions, one Google Sheet keeps everyone on the same page.
Other common reasons include switching from a Microsoft 365 subscription to Google Workspace, sharing data with someone who doesn't have Excel installed, making spreadsheets accessible from any device without desktop software, or simply backing up important data to the cloud.
Understanding the Excel File Format
Excel's modern file format (.xlsx) is actually a ZIP archive containing XML files that describe the spreadsheet's structure, data, styles, formulas, and charts. The older .xls format (Excel 97–2003) uses a binary structure called BIFF (Binary Interchange File Format) that's more compact but less accessible to other tools.
This converter uses SheetJS, an open-source JavaScript library, to parse both .xlsx and .xls files directly in your browser. It reads the workbook structure, extracts the data and computed formula values from each sheet, and outputs them as clean CSV (comma-separated values) — a universal plain-text format that Google Sheets imports perfectly.
What Carries Over (and What Doesn't)
CSV is a data-only format, which means cell values — including numbers, text, and dates — transfer cleanly. Formula results are preserved as their computed values (so if a cell shows $1,500 from a SUM formula, the CSV will contain 1500). However, the formulas themselves, conditional formatting, cell colors, merged cells, charts, images, and data validation rules are not included in CSV files. If you need to preserve formulas, the best approach is to upload the .xlsx directly to Google Drive, where Google Sheets can interpret most Excel formulas natively.
Common Use Cases
Migrating company data to Google Workspace: When organizations switch from Microsoft 365 to Google Workspace, hundreds of Excel files need to be converted. This tool lets you do it one file at a time, right in your browser, without uploading sensitive data to any third-party service.
Sharing data with clients or teammates: Not everyone has Excel installed, but everyone can open a Google Sheet link. Converting to CSV and importing into Sheets creates a shareable, cloud-accessible version of your data.
Cleaning up data for analysis: Sometimes you receive Excel files with heavy formatting that makes them hard to work with. Converting to CSV strips away the formatting noise and gives you pure data to import into Sheets, a database, or any other tool.
Archiving spreadsheets: CSV files are future-proof. Unlike proprietary formats that depend on specific software, CSV can be opened by any text editor, spreadsheet app, or programming language — making it ideal for long-term data storage.
