TOML to PROPERTIES Converter Online — Free & Private

Developer notes

• Input TOML must be a flat table of primitive values at the root. • Nested tables such as [database] with sub-keys fail with a flat-object error. • Choose = or : separator to match your Spring/Java toolchain. • For nested configs, use TOML → YAML or TOML → INI instead.

Conversion options

Use cases

• Emit application.properties from flat Cargo or pyproject snippets. • Support teams still on .properties while authoring TOML elsewhere. • Quick one-off exports without a build plugin.

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.
