Everything you need to know about DataFlip.
Is my data secure?
Absolutely. DataFlip is a **privacy-first** tool. Everything happens locally in your browser using JavaScript's `FileReader` and `papaparse`. Your data is never sent to any server.
Is there a file size limit?
Since processing happens on your device, the limit is governed by your browser's memory. Most modern browsers can handle JSON and CSV files up to several hundred megabytes with ease.
Do I need an internet connection?
Once the page is loaded, you can disconnect from the internet and continue converting. All logic is bundled within the application and runs offline in your browser.
