100% client-side Free forever No sign-up

Runs 100% in your browser — nothing is ever uploaded.

What is .env Diff?

Paste two .env files separated by a ----- line and instantly see which variables exist only in one file and which have different values — the classic "works locally, breaks in prod" debugging step. Comments and blank lines are ignored; quoted values are normalized before comparison.

How to use .env Diff

  1. Paste your two .env files (separated by -----) into the input box or click “Load sample” to try it.
  2. Adjust the options in the toolbar if needed (delimiter, table name, format …).
  3. Click the convert button — the diff report appears instantly in the output pane.
  4. Copy the result with one click or download it as a file.

ConvertLab FAQ

Is the .env diff tool free?

Yes — 100% free, no signup, no limits, no watermarks. Use it as often as you like.

Are quoted values compared fairly?

Yes — surrounding single/double quotes are stripped before comparing, so KEY=value and KEY="value" are correctly treated as equal.

Is my data uploaded to a server?

No. The conversion runs entirely in your browser with JavaScript — your data never leaves your device, which makes the tool safe even for confidential files.

Are these converters free?

Yes — every ConvertLab tool is 100% free with no signup, no limits and no ad walls.

Is my data uploaded anywhere?

No. All conversions (JSON, CSV, XML, YAML, INI, .env) run entirely in your browser. Nothing ever leaves your device.

Do these tools work offline?

Yes — once the page is loaded, every converter works without an internet connection.
