Spreadsheet converter
Open an XLSX, CSV or JSON file, check the preview and download the format you need.
Your files are not uploaded or stored: everything happens on this device and is gone when you close the tab. Privacy
Zero upload
Processing uses your device's CPU and memory. No file is ever sent to a server.
Big batches
Drop dozens or hundreds of images. The queue adapts to your device's power.
No artificial limits
No “5MB max” or “20 images at a time”. Your hardware is the only limit.
Installs as an app
Works offline after first use and opens like a native app on Windows, Mac, Android and iPhone.
