Extract environment variables from a .env file
Open the Env Variable Extractor for a .env file. Paste the text or upload the file, then review the parsed key-value table. The table keeps source details such as line numbers, comments, blank lines, duplicate keys, export prefixes, and quoting. The input stays in your browser and is not uploaded.
What Env Variable Extractor accepts
Paste environment-variable text into Env Variable Extractor or upload a .env file. It parses the source into a key-value table while retaining the source details needed to check each row against the original text.
What the table preserves
Line numbers, comments, blank lines, export prefixes, duplicate keys, and quoting remain visible in the parsed table. A duplicate key stays as its own row, and an export prefix remains part of the recorded source context. These details let you compare the table with the original file.
Values that look like secrets are masked by default. After reviewing the rows, export the parsed result as CSV or JSON.
Tasks the extractor supports
- Paste environment-variable text and inspect its parsed rows.
- Upload a .env file and compare its rows with the source line numbers.
- Review comments, blank lines, duplicate keys, export prefixes, and quoting in the table.
- Keep secret-looking values masked by default, then export the parsed rows as CSV or JSON.
When to use Config File Tools
Use Config File Extract Tools for environment variables in a .env file and the source details around them. Open Config File Tools for validation, comparison, merging, or conversion of YAML and TOML. Env Variable Extractor is the child page in this category.
