Question 1

What is an .env file?

Accepted Answer

An .env file is a simple text file that stores environment variables as key-value pairs (e.g., DB_HOST=localhost). It is commonly used in software development to configure applications without hardcoding sensitive values like API keys, database credentials, and feature flags.

Question 2

Is this .env editor safe for sensitive values?

Accepted Answer

Yes, NexTool's .env File Editor runs 100% in your browser. No data is ever sent to a server. Your secrets and API keys stay on your machine. You can also use the Mask Values feature to hide sensitive data while editing.

Question 3

What formats can I export to?

Accepted Answer

You can export your environment variables to .env (standard dotenv format), JSON, YAML, Docker --env-file format, and shell export commands. Just select the format from the dropdown and click Copy or Download.

Question 4

Can I import a .env file?

Accepted Answer

Yes, you can either paste .env content directly into the editor, or drag and drop a .env file from your computer. The tool will automatically parse all variables, comments, and empty lines.
