Env File Manager
Paste your .env file content below. Sort, deduplicate, find empty values, compare two files for conflicts, and export in multiple formats.
All processing happens in your browser — nothing is sent to our servers
How it worksEnvironment Variable File Parsing & Management
01Parse input
Split .env content by newlines — extract KEY=VALUE pairs, skip comments (#) and blank lines
→
02Detect issues
Identify duplicate keys, empty/missing values, and optionally compare against a second .env file for conflicts
→
03Process
Sort alphabetically (A-Z or Z-A), deduplicate by keeping first or last occurrence, highlight empty values
→
04Export
Convert to .env, Docker -e flags, Docker Compose YAML, Kubernetes ConfigMap YAML, or JSON object
Spec: dotenv convention (no formal RFC — de facto KEY=VALUE per line, # comments, optional quoting)
