Convert CSV to TOML online — browser-local
Paste CSV and get TOML output with zero server uploads. Everything runs locally in your browser.
Developer notes
• Validate inputs upstream. • Reverse conversions may be lossy depending on format. • Large files: prefer desktop browsers.
Use cases
• Quick prototyping between formats. • Lightweight CI pipelines without middleware. • Config review before commit.
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 + whether row 1 holds column names (Auto delimiter follows locale only for convenience). 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.
