Bash Properties to JSON Converter

Paste shell variable assignments — a sourced config file, /etc/default/*, os-release, a systemd EnvironmentFile or a block of export lines — and get a JSON object. Conversion runs in your browser; nothing is uploaded.

How the conversion works

Both NAME=value and export NAME=value are read.
Matching quotes are removed: 'hello world' and "hello world" both become hello world.
Comments (#, including a #!/bin/bash line) and blank lines are skipped.
Only valid variable names are read — letters, digits and _, not starting with a digit. Other lines, such as commands or function definitions, are ignored.
Values stay strings, exactly as the shell would see them.

Example

#!/bin/bash
export APP_NAME="demo"
export APP_PORT=8080
DB_HOST=localhost
export GREETING='hello world'

becomes

{
  "APP_NAME": "demo",
  "APP_PORT": "8080",
  "DB_HOST": "localhost",
  "GREETING": "hello world"
}

What is not evaluated

The file is read as text, never executed. That keeps it safe, but it means shell features are not expanded:

$HOME or ${VAR} references stay as literal text.
Command substitutions such as $(date) are not run.
Values spanning several lines and arrays (ARR=(a b c)) are not supported.

When to use it

Inspect or document the variables a deploy script sets.
Migrate shell-based configuration to a JSON or YAML config file.
Compare environments — convert two config files and diff the JSON.
