Frequently Asked Questions

Why do these tools run in the browser?

Traditional tools upload your files to remote cloud servers, creating privacy, security, and latency issues. DataForge uses modern JavaScript, Web Workers, and local memory so your data stays 100% on your machine.

Is there a file size limit?

Because processing occurs in your browser's RAM, files up to 100MB+ or several hundred thousand rows typically process smoothly on standard laptops and desktops.

Are these tools really free?

Yes. All core CSV, Excel, and JSON transformation utilities are completely free to use with no accounts, no credit cards, and no usage caps.
