.env Key Sorter Guide
Sort the keys in a .env file alphabetically, keeping each comment with its key and optionally dropping duplicates or aligning values.
A short companion for .env Key Sorter: when it is useful, what it expects, and what to check before using the result.
What it does
Put a .env file in alphabetical order without shuffling the comments that belong to each setting. The top comment block stays first, a comment above a key travels with that key, and blank lines are closed up. Duplicate keys can be collapsed to the last value, and the equals signs can be lined up for a tidier read.
Use the tool
Open .env Key Sorter, add the input the tool asks for, run it, and check the output before using it elsewhere.

Questions
Does it change the values?
No. Only whole lines are moved, so spacing, quotes and inline comments inside a value are untouched. Alignment only pads the space before the equals sign.
Which duplicate value wins?
The last one, which is what most .env loaders use when a key appears twice.
Is my file uploaded?
No. The file is read, sorted and written in the browser; nothing leaves the page.
Does it understand export?
Yes. A line like export PORT=3000 is still recognised as the PORT key and keeps its export prefix.
