FAQ

Finding the right utility

?Where should I start when I know the task but not the tool name?

Browse a task category, then open a tool whose input and output match what you need. For example, formatting JSON and converting JSON to CSV solve different problems.

?Why do some tools show limitations before I start?

Outputs depend on the implementation and input type. Read the tool-specific limitations before uploading files, submitting links, or relying on a calculation.
