What this tool helps you do
Compare two flat environment configurations before moving a small application between environments. The report separates added keys, removed keys, changed assignments and an unchanged count. Values are redacted by default, making it easier to discuss configuration drift without copying credentials into a report. The conversion runs locally and does not send the configuration to a conversion API.
Format rules and limitations
This supports one assignment per line, optional export prefixes, comments and single-quoted or JSON-escaped double-quoted values. Multiline values, duplicate keys and malformed assignments are rejected. It does not expand variables, read process environment settings or interpret shell commands. Exact parsed string values are compared, so intentional differences such as whitespace inside quotes remain meaningful. Enabling value display includes those strings in the downloadable result; review it before sharing.
