FAQ

Questions from developers

Is my data safe to paste into these tools? +
The JSON, XML, binary, and text tools process your input in the browser and do not transmit your data to a server for storage or logging. You can safely use these tools with development data, config file contents, and API responses. We don't log tool inputs. For highly sensitive production secrets, the same caution applies as with any online tool but for typical dev work, these tools are safe to use.
Do I need an account to use the developer tools? +
No account needed for any developer tool. Open the URL, use the tool, done. There's no login wall, no free trial that expires, and no usage counter. Creating a free account (no cost, no credit card) gives you 100 tool uses per day tracked per session if you want that, but it's never required.
What's the difference between the JSON Formatter, Beautifier, and Validator? +
The JSON Formatter formats JSON with proper indentation and readable structure, it's for making minified or messy JSON readable. The JSON Beautifier does the same with additional options for indent size and output style. The JSON Validator checks whether your JSON is syntactically valid according to the JSON spec, it will tell you exactly where an error is if the JSON is malformed. In practice, most developers use the Formatter most frequently, and reach for the Validator when a tool is rejecting their JSON and they can't see why.
Are there API limits or rate limits on these tools? +
There are no API limits because these tools don't have a public API, they're browser-based utilities. As browser tools, they process input locally and have no rate limiting. A free account allows up to 100 tracked tool uses per day, but this is a soft session limit and not enforced for simple formatting tasks. These tools are not intended for programmatic batch processing for that, you'd want a dedicated API or a command-line tool.
Can I use these tools for work projects or commercial use? +
Yes, completely. There are no personal-use-only restrictions. Use these tools on client projects, for your employer, in agency work or for commercial development with no attribution required. The tools are free for everyone.
