What are INI and .ENV files and how they work
INI files are simple configuration files composed of key-value pairs grouped into optional bracketed [section] blocks. Originating in MS-DOS and Windows, INI syntax remains widely used in PHP (php.ini), MySQL (my.cnf), desktop software, and game engines.
Dotenv (.env) files are simplified configuration files containing key-value pairs (e.g. DATABASE_URL=postgres://...) designed to inject environment variables into applications across Node.js, Python, Docker, and Kubernetes environments.
How to parse and extract keys from INI and .ENV files
- Load your config text or file. Drop a .ini, .env, .cfg, or .conf file onto the box or paste your raw configuration text.
- Click Parse & Extract Config. The browser parses section headers ([section]), strips comments (; or #), and extracts key-value pairs.
- Select your output format. Convert your configuration into nested JSON, flattened dot-notated JSON, normalized .ENV format, or a 3-column CSV table.
- Export or copy the result. Copy the converted configuration to your clipboard or download the file instantly.
What the INI extractor extracts
- Sections & Namespaces: Extracted into distinct parent JSON objects.
- Key-Value Pairs: Cleanly separated keys and values with automatic type parsing for booleans (
true/false) and numbers. - Comments Filtered: Strips line comments beginning with semicolons (
;) or hashes (#). - Export Options: Nested JSON, Flat Key-Value JSON, Clean .ENV format, and tabular CSV.
Supported configuration formats
- File Extensions:
.ini,.env,.cfg,.conf,.properties,.cnf. - Comment Styles: Semicolon (
;) and hash (#) comments. - Quoting: Handles single and double-quoted values containing spaces or special characters.
Why local in-browser parsing is essential for configuration files
Configuration files and .env files frequently contain database passwords, API credentials, secret tokens, and private hostnames. Uploading these files to remote servers creates severe security liabilities.
EasyExtract executes all parsing locally in your browser's memory using client-side JavaScript. No keys, secrets, or file contents are ever uploaded or transmitted.
What this tool does not do
- It does not execute shell command substitution (e.g.
VAR=$(command)). - It does not validate database connections or verify external credentials.
Common uses for INI and .ENV extraction
- Converting .env to JSON: Generating JSON config payloads for AWS Secrets Manager, Doppler, or HashiCorp Vault.
- Auditing Config Files: Inspecting legacy
php.ini,my.ini, or Git config files. - Docker & CI/CD: Formatting environment variables for Kubernetes ConfigMaps and GitHub Actions.
INI extraction compared with YAML and JSON tools
If your configuration file uses indentation instead of brackets, use the YAML data extractor. For JSON files, use the JSON field extractor.

Frequently asked questions
What is the difference between an INI file and a .ENV file?
An INI file supports grouped sections ([section]) and uses semicolons or hashes for comments. A .ENV file is a flat list of KEY=VALUE pairs designed for application environment variables.
Can I convert a .env file to JSON?
Yes. Paste your .env file or drop it into the extractor, and the tool will convert all environment variables into a clean JSON object.
Are my API keys and secrets safe?
Yes. All extraction happens 100% locally in your browser. No data is ever transmitted, logged, or stored on any server.
How does the tool handle comments in INI files?
Lines starting with ';' or '#' as well as inline comments are automatically recognized and stripped from the structured output.
Does it support typed values like booleans and numbers?
Yes. Values like 'true', 'false', 'yes', 'no', 'on', 'off', and numeric strings are converted to their appropriate JSON data types.
Can I export INI data to CSV?
Yes. Select CSV as the export format to download a 3-column table containing Section, Key, and Value columns.
What file types can I upload?
The tool accepts .ini, .env, .cfg, .conf, .properties, and .cnf configuration files.
