What this is

A JSON converter that runs in your browser. Nothing you paste is uploaded.

Five outputs, two levels of care

OutputWhereBehaviour
CSVHome pageConvenience converter. Columns come from the first object only, every cell is JSON-encoded, nested values become JSON text.
SQL INSERTHome pageOne statement per object, string values single-quoted with ' doubled. Nested values print as [object Object].
Flat JSONTool pageDotted-path keys: user.address.city, tags[0].
YAMLTool pageBlock style; strings YAML 1.1 would retype are quoted.
XMLTool pageArrays repeat the element; illegal key names are rewritten and counted.

The home-page CSV and SQL converters keep their original, simple behaviour on purpose; the guide to their edges lists them. If you need correct CSV quoting for commas and newlines, use a dedicated CSV writer.
