Environment files do not error. A space inside a value, a quote placed wrong, or an invalid variable name and the file “loads” while carrying the bug into runtime. That is the cruelest kind of config failure.
Paste the KEY=VALUE file and it parses each line, flags invalid names, and exports the result as JSON. It turns the silent misparse into a visible report before deploy.
