Format Converters
Formatters and converters for everyday data work: pretty-print JSON, validate a structure against a schema, turn a CSV export into JSON for an API, convert tables between YAML and JSON, format a SQL query or minify code before shipping. Syntax errors are highlighted immediately — convenient for debugging configs and API responses.
