What this tool does
INI Viewer opens an INI configuration file and lays out the sections and key-value pairs so settings are easy to read. See where each section starts and what each key is set to, which is handy when you are checking an app or game config without hunting through plain text.
How it works
Paste text or open an .ini file. The viewer groups keys by section, shows their source line numbers, and flags duplicate sections or keys. Search the settings or filter by section, then copy or download JSON, CSV, or normalized INI text. Parsing and export run in your browser.
When to use INI Viewer
Checking an app or game configuration file
Reading the sections and keys in an .ini
Reviewing settings before you change them
Opening a config file on any machine
FAQ
Is this a full INI validator?
It flags common issues such as duplicate sections and keys. INI dialects differ between applications, so warnings are a review aid rather than proof that a configuration is valid for a particular app.
Can I convert an INI file to JSON or CSV?
Yes. Use the JSON or CSV export controls after reviewing the parsed values. Check duplicate keys and application-specific syntax before relying on the exported data.
Can it read other config types?
For mixed config formats, try the Config File Viewer.
Are my files uploaded anywhere?
No. The file is parsed in your browser and never leaves your device.
