Frequently asked questions about data conversion
Is there a file-size limit for conversions?
Because conversion happens in your browser, the practical limit is your device memory rather than a server cap — most files convert instantly.
Will converting change or reorder my data?
No. The converters preserve your keys, order and values; they only change the format, not the content.
Is my data uploaded anywhere?
Never. All conversion runs client-side, so your data stays on your device.
