Use the share bar under any tool's output to post a link to X/Twitter, LinkedIn, Facebook or Reddit, or copy a permalink to your snippet.
Troubleshooting
My formatted output looks wrong or incomplete
Ensure your input is valid for the target format — for example, JSON formatters require valid JSON. Error alerts appear inline; fix the highlighted issue and the output updates automatically.
The tool says my input is invalid
Check for common issues like trailing commas in JSON, unescaped characters in URLs, or mismatched brackets. The error message points to the location of the problem.
My saved workspaces aren't showing up
Workspaces are tied to your account. Make sure you're signed in with the same account you used to create them, and check the Workspaces page filters and folder view.
Sharing a link doesn't show my output
If you weren't signed in when you shared, the link points to the tool rather than your specific output. Sign in first to generate a permalink to your actual snippet.
The app feels slow on a large input
Very large payloads can slow down live formatting. Try pasting a smaller chunk, or disable live updates while editing and re-enable when ready.
