How to choose the right tool

Start with the job you need to finish, then narrow by category, search terms, or AI features if you want help with generation, analysis, calculation, or conversion. If you already know the format you are working with, look for tools that match the exact task - like converting dates, cleaning JSON, or formatting text - so you get fewer controls and a faster result.

Most tools here are best for quick, single-purpose work in the browser. When you are comparing options, check the short descriptions and tags first: they usually tell you whether a tool is built for calculation, cleanup, validation, or generation.
