JSON to Env Conveter

The JSON to .env Converter Tool is a powerful utility designed to streamline the conversion of JSON formatted data into .env environment variable format. This tool is particularly useful for developers and system administrators who need to manage and configure environment variables efficiently. By providing a straightforward interface, it simplifies the process of generating environment variable files used in various applications and deployment scenarios.

Data Privacy Notice:
Your data won't be stored by us. We respect your privacy and ensure that all data you input is processed solely for the purpose of conversion and is not stored or used beyond the immediate session. Your JSON data and the resulting .env output are not kept or shared. Feel confident using this tool knowing your information is secure and confidential.

JSON to .env Converter - User Guide

Step 1: Paste Your JSON

In the "Paste your JSON" textarea, paste your JSON data.
You can paste:

• A single JSON object, e.g., { "DATABASE_URL": "...", "API_KEY": "...", "PORT": 3000 }
• An array of JSON objects, e.g., [ {...}, {...} ]
• Nested objects inside objects (supported)

Step 2: Set Number of Parameters to Include

Use the "Number of parameters to include from each object" input box.
Default is 2.
This limits how many key-value pairs from each object are included in the output.
Increase this number if you want more keys included.

Step 3: Decide Whether to Include Nested Keys

Choose "Include nested objects keys?":
Yes - includes keys inside nested objects using dot notation (e.g., parent.child=value).
No - includes only top-level keys from each object.

Step 4: Choose Key Case Format

Select the format for the keys (not values):

• Original - keeps keys as-is.
• UPPERCASE - converts all keys to uppercase.
• lowercase - converts all keys to lowercase.

Use this to match your environment’s requirements.

Step 5: Validate Your JSON

The Convert button is disabled until valid JSON is detected.
If your JSON has syntax errors, an error alert will guide you to fix it.
The tool may auto-wrap JSON snippets in arrays if needed.

Step 6: Convert JSON to .env

Click the Convert to .env button.
A 2-second loading spinner shows progress.
The converted .env text will appear in the output box below.

Step 7: Use the Output

• Copy the output to clipboard.
• Clear input and output to start fresh.
• Download the output as a .env file.

Additional Tips

• Array inputs: If your JSON is an array of objects, all objects will be processed.
• Nested objects: Enable nested keys to flatten nested objects using dot notation.
• Parameter count: Controls how many keys per object to include — helps exclude unwanted keys like PORT.
• Case format: Useful to enforce uppercase or lowercase keys in output.
• Error messages: If JSON is invalid, the tool shows clear errors for correction.

Example Workflow

Input JSON:

[
  {
    "DATABASE_URL": "postgres://user:pass@localhost/db",
    "API_KEY": "abc123",
    "PORT": 3000,
    "settings": {
      "debug": true,
      "version": "1.0"
    }
  }
]

    

Settings:

• Parameters to include: 3
• Include nested keys: Yes
• Keys case: UPPERCASE

Output .env content:

DATABASE_URL=postgres://user:pass@localhost/db
API_KEY=abc123
SETTINGS.DEBUG=true

    

Explanation: Only first 3 keys included per object, nested keys flattened, keys uppercased.
