INI to TOML Converter Online — Free & Private

Convert sectioned INI configs to TOML tables locally — ideal for Cargo.toml or pyproject.toml workflows.

Loading…
INI → TOML — sections to tables
Convert INI config files to TOML — [section] headers map to TOML tables for Cargo-style configs.

Developer notes

• [database] sections become [database] TOML tables. • Flat root keys stay at the TOML root. • Toggle Sort TOML keys for deterministic ordering on root keys. • Output from this tool is not valid input for INI → Properties.

Conversion options

Sort TOML keys
Alphabetically sort top-level TOML keys for stable, diff-friendly output.

Use cases

• Move legacy INI configs toward Cargo.toml or pyproject.toml workflows. • Preview TOML structure from Windows/PHP INI exports. • GitOps teams standardising on TOML while ingesting INI.

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.

Examples

Canonical flat keys (Sort TOML keys)

Input

zebra = last alpha = first mango = mid beta = second gamma = third delta = fourth epsilon = fifth zeta = sixth

Output

zebra = "last" alpha = "first" mango = "mid"

Database section

Input

[database] host = db.internal port = 5432 ssl = true

Output

[database] host = "db.internal" port = 5432 ssl = true

Sections preserved

Do INI sections become TOML tables?

Yes — each [section] maps to a TOML table header with keys underneath.

What does Sort TOML keys affect?

Reorders top-level keys alphabetically — use the zebra/alpha/mango sample on flat INI.

Can I paste this output into INI → Properties?

No — sectioned TOML is not flat INI. Use INI → Properties only for flat key=value INI.
