TOML to INI Converter Online — Free & Private

Generate INI from object-shaped TOML — one nesting level maps to [section] blocks; deep nesting may emit [object Object] without failing.

TOML → INI — object-shaped TOML
Convert object-shaped TOML to INI — one level of nesting maps to [section] headers; deeper nesting is risky.

Developer notes

• Top-level TOML tables with one nesting level map to [section] INI blocks. • Deep nesting (>1 level) or arrays inside sections may become [object Object] strings without failing — avoid those inputs. • Samples use one-level tables only. • No formatting options in v1.

Use cases

• Export Cargo or pyproject snippets to legacy INI consumers. • Quick INI drafts from flat TOML toolchains. • Validate object-shaped TOML before hand-editing 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

One-level database table

Input

[database] host = "db.internal" port = 5432 ssl = true user = "app" password = "secret" pool = 10 timeout = 30

Output

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

Root scalar plus section

Input

environment = "production" [features] checkout-v2 = true dark-mode = false

Output

environment=production [features] checkout-v2=true dark-mode=false

One nesting level

What happens with deep nesting?

Values deeper than one level may stringify to [object Object] without an error — do not trust silent output; reshape upstream.

Are there formatting options?

Not in v1 — fixed key=value and [section] rules.

Can TOML arrays map to INI?

No reliable mapping — object-shaped TOML without root arrays is required.
