TOML to JSON Converter Online — Free & Private

Developer notes

• TOML `#` comments are dropped — output is strict JSON with no comment syntax. • Single TOML document per paste. • Use compact JSON for logs or indented JSON for reviews. • Round-trip with JSON → TOML to verify shape.

When teams pick this route

• Feed TOML configs into JSON-only validators. • Compare Cargo.toml changes as JSON trees. • Bridge Rust/Python configs into JS tooling.

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.
