Your files stay on your device

.env inspector and formatter

Parse a .env file and get it back clean: every duplicate key, export prefix, quoting rule, and shell-hostile name is named in a loss ledger instead of silently normalizing.

Mode

Parse, ledger, canonical rewrite.

.env text
dotenv-family semantics, hand-rolled (the dotenv package imports node:fs)
What this tool does not do
  • Nothing is evaluated or interpolated. $VARS stay literal text; what a loader does with them is the loader’s business.
  • No secret checking and no “looks like a key” scanning, but a real .env pasted anywhere is a secrets handoff. It stays in this tab’s memory until you leave: a browser tab cannot guarantee zeroization, so clear the tab when done.
  • The duplicate-key note states the real split: dotenv keeps the FIRST value, docker compose env_file keeps the LAST.
Paste, drop, or type to begin. Everything stays on this device.
