.env ↔ JSON Converter
Convert between .env files and JSON/YAML format.
How to Use
- Paste your .env content or JSON object into the input panel. The tool auto-detects the format: lines with KEY=VALUE are treated as .env; input starting with ｛ is treated as JSON.
- Click Convert (or type — it updates live). Comments and blank lines in .env files are ignored. Quoted values (single or double quotes) are correctly unquoted during conversion.
- Copy the output. When converting to .env, values containing spaces are automatically wrapped in double quotes. Use the Clear button to reset both panels.
Frequently Asked Questions
- Are comments in .env files preserved?
- Comment lines starting with # and blank lines are silently skipped during .env to JSON conversion. They cannot be round-tripped back because JSON has no comment syntax.
- Are .env value types preserved?
- All values are treated as strings in both .env and JSON output. Numeric-looking values like PORT=3000 become "3000" in JSON. If you need typed values, edit the JSON manually after conversion.
- Is there a size limit?
- No hard limit. Very large inputs may slow your browser.
