Developer & Data Conversion Tools
Developer workflows are full of small format and inspection tasks that are annoying to do by hand but too common to keep rebuilding from scratch. You might need to turn CSV into JSON, decode a JWT from an API response, generate a cron schedule, hash a payload, or test a regex before shipping it into code. This hub groups those practical browser-based utilities with the existing time and data helpers so you can move from raw input to copy-ready output faster.
