How I sort .env files without moving comments to the wrong place

A messy .env file makes configuration harder to review. Sorting helps, but comments and duplicates need care.

The .env Key Sorter tool gives me a safe place to test the idea before I put it into a script, server, or production workflow.

The simple mental model

A messy .env file makes configuration harder to review. Sorting helps, but comments and duplicates need care.

My checklist

Before I trust the result, I check:

• Paste the .env content.
• Keep comments attached to the key they explain.
• Sort keys alphabetically.
• Decide what to do with duplicate keys.
• Optionally align values for readability.
• Review secrets before sharing output.
• Commit config examples, not real production secrets.

The tool saves time, but the important part is still understanding the input and reviewing the output before using it somewhere important.
