.env Sorter
Sort keys in a .env file and find duplicate keys.
Category: Dev Tools
When to use?
Use it to sort a long environment file by key name and find duplicate settings to reduce deploy mistakes.
How to use
- Paste the environment variable content.
- Sort by key.
- Check the duplicate-key list.
Input Explanation
Enter .env content in KEY=value form.
Calculation Basis
It extracts the key before = from non-comment lines, sorts ascending by key, and counts duplicates.
Usage Examples
- Check env variables - Tidy local and deploy .env files.
- Quick pre-deploy check - Check inputs and output to reduce errors before dev/ops work.
- Aid docs/reviews - Copy the result into dev docs, issues, or review comments.
Examples
- B=2, A=1 → A=1, B=2
- A .env file with scrambled key order → sorted alphabetically for readability
Cautions
- Generated output is for reference; test carefully before production use.
- .env sorting runs only in the browser and secret values are not sent out.
FAQ
Are comments sorted?
The result focuses on actual variable lines.
Is the pasted env sent out?
No. .env sorting runs only in the browser, so secrets are not sent out.
Does it find duplicate keys?
It flags keys that appear more than once so you can spot unintended duplicates.
Can a value contain an equals sign?
Only the first = is the key/value separator, so extra = signs in the value are kept.
