All Developer Converters
17 free format converters for JSON, CSV, XML, YAML, HTML entities, URL encoding, colors, and more. Everything runs in your browser.
Private format conversion
Developer conversion tasks often involve API payloads, logs, CSV exports, or snippets from a private project. These tools are built for quick browser-side conversion so you can clean up data, inspect structure, or transform formats without uploading the content to a server or creating an account.
Best uses
Use these converters for everyday development chores: JSON to CSV exports, XML inspection, YAML conversion, URL encoding, HTML entity cleanup, and color format changes. For production migrations, validate the output in your application or test suite before replacing source data.

What these converters are not
These tools are meant for small to medium snippets and fast inspection, not for processing sensitive production databases or massive files. If the data controls money, authentication, customer records, or compliance workflows, use the converter for a preview and then run a reviewed script in your own environment for the final transformation.
For best results, paste a small sample first, confirm the structure is preserved, then convert the full snippet. If the input is malformed, minified, or missing required delimiters, fix that source issue before trusting the converted output.
