Environment Variable Formatter
Paste key value pairs and convert them into common environment variable formats.
One list of variables, every format
The same set of configuration values has to appear in several shapes — a .env file, shell exports, a Docker Compose block, a CI settings panel. Reformatting them by hand between each is tedious and error-prone. This tool takes your key-value pairs once and converts them into the common environment-variable formats you need.
That saves the fiddly work of adding or stripping quotes, prefixes, and export keywords, and it keeps the values consistent across every environment so a typo in one place does not cause a bug you chase for an hour.
Private and instant
Formatting runs entirely in your browser, so secrets and configuration values are never uploaded — safe for the real keys you would never paste into an unknown website.
Frequently Asked Questions
What formats can this create?
It converts key value pairs into .env, shell export, Docker Compose environment, and JSON formats.
Does it validate secrets?
No. It formats variables and flags duplicate or invalid-looking keys.
Should I paste real production secrets?
Avoid pasting sensitive production secrets into any tool unless you are sure of the environment. This tool runs locally, but caution is still wise.
Is anything uploaded?
No. Formatting happens locally in your browser.
