.env / dotenv editor

Client

Clean up sample environment files: spot duplicate keys, sort variables, and preview nested JSON without leaving the tab. Redact secrets before sharing—this page does not validate against a specific framework loader.

What this does

Work on KEY=value environment files in the browser: highlight duplicate keys, sort and dedupe lines, preview nested JSON, or replace the editor from a JSON object—without uploading secrets to a server.

.env editor

?

Parse and tidy KEY=value files locally. For one-shot conversion only, you can also use .env → JSON or JSON → .env in the JSON hub.

Nearby workflows on Toolcore

  • .env → JSON — for a focused one-way conversion in the JSON hub.
  • JSON → .env — when JSON is the source of truth and you only need export lines.
  • JSON formatter — to pretty-print JSON before importing it here.

Common use cases

  • Normalize a messy .env.example before committing it to a public repo (no real secrets).
  • Sort keys alphabetically so diffs stay readable across branches.
  • Collapse duplicate keys after merging branches—last value wins when you dedupe.
  • Import a small JSON config object and emit flat KEY=value lines for local templates.

Common mistakes to avoid

  • Pasting production secrets into any online editor

    Treat pasted values as sensitive. Prefer sanitized examples; rotate anything that leaked.

  • Expecting full dotenv spec support

    Export prefixes, quotes, and dot-nested keys are handled pragmatically—not every edge case from all loaders.

  • Replacing a secrets manager

    Use your platform vault for production. This tool helps text editing and JSON interchange, not access control.

FAQ

Is my .env file uploaded?

No. Parsing and edits run entirely in your browser.

How is this different from JSON → .env in the JSON hub?

Hub pages are one-shot converters. This editor keeps you in a workspace with sort, dedupe, issues, and JSON import.

Can I explain what variables mean?

Redact values first, then try the environment-lines explainer under AI tools if your site has it enabled.
