JSON to CSV Converter Online — Free & Private

Developer notes

• Only objects or arrays-of-objects flatten predictably. • Single-key JSON/XML wrappers (e.g. `{ "orders": [ {...} ] }`) unwrap to row arrays automatically. • Primitive tops or heterogeneous arrays trigger guidance to reshape first. • On **/fr/** routes, CSV uses `;` between columns for European spreadsheet defaults (Numbers, Excel FR). • Split giant exports offline before expecting tab performance.

When teams pick this route

• QA merging webhook payloads into spreadsheets. • RevOps marrying CRM JSON blobs with CSV templates. • Support pairing tickets with summarized exports.

About these options

CSV exports: choose a delimiter (Auto follows locale — semicolon on /fr), RFC-minimal vs always-quoted fields, line endings, and whether to emit a header row. CSV imports: delimiter is auto-detected from the first line (comma, semicolon, tab, or pipe) — toggle whether row 1 holds column names. JSON output (XML, YAML, or CSV sources): indentation (including compact one-line) and optional recursive key sort. JSON → XML: toggle pretty-printing and indent width. YAML output: indent width, readable vs tighter layout, and deterministic string quoting (there is no source YAML file to “preserve”). XML comments are not represented in the intermediate JSON tree.
