INI to PROPERTIES Converter Online — Free & Private
Flat INI only (no [sections]) — convert key=value INI lines to Java .properties; for sectioned INI configs, use INI → TOML or INI → YAML instead.
Developer notes
• Input must be flat INI (key = value lines only) — no [section] headers. • Sectioned INI parses to nested JSON and fails at Properties export. • Choose = or : separator to match your Spring/Java toolchain. • For [database] style configs, use <a href="/en/ini-to-toml">INI → TOML</a> or <a href="/en/ini-to-yaml">INI → YAML</a>.
Conversion options
Use cases
• Legacy flat INI files that must become application.properties. • Support teams still on .properties while receiving flat INI snippets. • 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.

Flat INI required
Why does sectioned INI like [database] fail?
Java .properties is flat. INI sections become nested objects that cannot map to .properties — use INI → TOML or INI → YAML for sectioned configs.
Can I use : as separator?
Yes — toggle Key/value separator in options (= default, : optional).
Is INI → TOML output valid here?
No — TOML with [database] tables is not flat INI. Do not paste INI → TOML output into this tool.
Uploads?
