About CSV to Excel

Convert a CSV file to Excel (.xlsx).

CSV to Excel is part of Smart2Office's suite of free browser-based utilities. It is designed to handle everyday tasks that would otherwise require installing dedicated desktop software or subscribing to a paid service. Open the page, use the tool, and close it — there is nothing to set up and nothing to maintain.

It works on any modern device — Windows PC, Mac, iPhone, Android phone or tablet — because it runs entirely in your web browser. That also means there is no version to update, no compatibility issues between operating systems, and no licence to renew.

✅ Key Features

  • Convert spreadsheet formats without installing Microsoft Office
  • Preserves column structure and data types accurately
  • Handles files with thousands of rows quickly
  • Free alternative to paid desktop converters

💼 When to Use This Tool

  • Preparing a database CSV export for analysis in Excel
  • Converting legacy Excel files to CSV for import into other tools
  • Sharing data across teams that use different spreadsheet software
