JSON, YAML, XML, CSV & SQL

Format, validate and convert the data formats that move between services: JSON, YAML, XML, CSV and SQL. Each converter tells you when something cannot be represented instead of quietly changing it.

Where it is used: Used wherever services exchange data: API payloads, config files, exports and database imports. Fast, lossless conversion saves a lot of squinting at brackets.
