FAQ

Frequently Asked Questions

Is my data sent to any remote server or stored in a database?

No. All 41 conversion, diffing, query, and validation algorithms execute 100% locally in your web browser using client-side JavaScript. Your data never leaves your machine.

Can I format, minify, and compare files?

Yes! Our suite includes dedicated formatters, minifiers, validators, and structural diff comparators for JSON, YAML, XML, CSV, and .ENV files.

How many developer tools are available?

There are 41 active, fully working developer utilities in the suite, discoverable through our central /tools directory and header mega menu.

Does the CSV converter handle quotes and multiline fields?
