Auto-Convert CSV to XLSX is a Chrome extension developed by DynamicL. This free browser add-on allows users to automatically convert downloaded CSV files to XLSX format.

With version 1.0, getting started is easy. Simply install the extension from the Chrome Web Store, enable "Allow access to file URLs" in the "Manage Extensions" settings, and you're ready to go. The entire conversion process takes place client-side in the browser, ensuring that your data never leaves your computer.

This extension offers reliable, accurate, and fast CSV to XLSX conversion. It also provides customizable options, including a domain white list for specifying which domains the extension should work on. Users can choose to delete the CSV file after conversion and append a timestamp to the filename.

Auto-Convert CSV to XLSX credits the use of Papa Parse and zipcelx libraries for its functionality. For any questions or feature requests, users can open an issue or contact the developer directly on GitHub at
