Developer tools and guides

What belongs in developer tools

These are the tools you reach for when the thing on your clipboard is meant for a machine: an API response that will not parse, a SQL dump you need as JSON, a token you want to read before you trust it, or a regular expression that matches one line too many. Each one works on text you paste or a file you open, and each one runs entirely inside this browser tab. Nothing you paste is sent to a server, which matters more here than almost anywhere else, because a JWT, a connection string or a customer export is exactly the kind of text that should never leave your machine.

The line between this section and text and data tools is drawn by what you are trying to do, not by the file extension. Turning a spreadsheet into CSV for a colleague is office work and lives with the text tools. Turning that same CSV into SQL INSERT statements or JSON for a database is developer work and lives here. Formatters and minifiers for JSON, XML, HTML, CSS, JavaScript and SQL come first, then validators and testers, then encoders, decoders and hash generators, and finally the conversions between structured data formats.

Every tool has its own address, so you can bookmark the one you use and link straight to it from a README, a ticket or a code review comment.
