Common Questions
Is the tool really free?
Yes. jsontofile.com is completely free with no limits, no signups, and no paywalls. All conversion happens in your browser.
Where is my data stored?
Nowhere. Your data never leaves your device. All processing is client-side JavaScript.
Can I request a new converter?
Absolutely. Email us with the formats you need and we'll consider adding them.
Is there an API?
Since all conversions are client-side, there is no server API. All the open-source libraries we use (SheetJS, PapaParse, js-yaml, fast-xml-parser) are available for you to use directly in your own projects.
