Environment template generator
Create a value-free .env.example from an environment file. Keep the variable names and remove defaults, comments and secrets.
Portable dotenv dialect: ASCII names, optional export, = assignments, # comments and literal single/double-quoted multiline values. No escape conversion, variable interpolation, shell execution or Docker Compose semantics. Up to 10,000 assignments. Use # empty for no assignments. Runs on your device with no configuration, repository or credential lookups. Up to 1,000,000 input characters and 4,000,000 characters per output file. Paste text to process locally. Review the supported syntax and the result before downloading. Results update as you type. Up to 1,000,000 characters.

How to use Environment template generator
- Paste the source environment file.
- Resolve any malformed or duplicate assignments.
- Download .env.example and review its variable names before sharing.
Useful next steps
Extract the names your configuration uses
Paste a valid environment file in the supported portable dotenv dialect. The output retains each variable name in source order and follows it with an empty = assignment. Optional export prefixes are removed.
Leave values and comments behind
Values, quoted multiline content, defaults and comments are omitted from the template. A secret written in a comment is not copied. The report contains only counts and fixed diagnostics; it does not include original values.
Resolve ambiguity before generating a template
Malformed assignments or duplicate names block the template instead of guessing which entry to keep. The resulting .env.example documents observed names, not a verified list of every variable required by your application. Review names before sharing them.
