Overview
The Object Key-Value Converter is a versatile utility designed to transform, restructure, and reformat object data between various standards like JSON, JavaScript objects, and environment variables.
When to Use
- •Standardizing object keys into a consistent naming convention like camelCase or snake_case.
- •Converting configuration objects into environment variable formats or properties files for deployment.
- •Swapping keys and values or extracting specific data structures for API integration.
How It Works
- •Paste your source data into the input field and select the corresponding input format.
- •Choose a conversion mode to manipulate the structure, such as swapping keys and values or converting to entries.
- •Apply case transformations to keys or values and select your desired output format.
- •Click convert to generate the processed object data in your chosen syntax.
Use Cases
Refactoring configuration files for cross-platform compatibility.
Preparing data payloads for frontend state management.
Generating environment-specific configuration strings from JSON templates.
Examples
1. Standardizing API Response Keys
Frontend Developer- Background
- An API returns data with inconsistent naming conventions, mixing snake_case and PascalCase.
- Problem
- The frontend application requires all keys to be in camelCase for consistency.
- How to Use
- Paste the JSON response, set Key Case Transform to 'camelCase', and select 'JSON (Pretty)' as the output.
- Example Config
-
inputFormat: json, keyCase: camel, outputFormat: json - Outcome
- A clean, standardized JSON object with all keys converted to camelCase.
2. Generating .env File from JSON Config
DevOps Engineer- Background
- A project configuration is stored in a JSON file, but the deployment pipeline requires a .env file.
- Problem
- Manually converting nested JSON to flat environment variables is error-prone.
- How to Use
- Upload the JSON config, set Output Format to 'Environment Variables', and choose your preferred separator.
- Example Config
-
inputFormat: json, outputFormat: env, separator: = - Outcome
- A formatted string ready to be saved directly into a .env file.

FAQ
What input formats are supported?
The tool supports JSON objects, raw JavaScript objects, and standard key-value pairs.
Can I change the casing of my keys?
Yes, you can transform keys into lowercase, UPPERCASE, camelCase, snake_case, kebab-case, or PascalCase.
Does this tool support environment variable output?
Yes, you can select 'Environment Variables' as the output format to generate key=value strings suitable for .env files.
Can I sort the resulting object?
Yes, you can sort the output by keys or values in either ascending or descending order.
Is my data sent to a server?
No, all processing is performed locally in your browser to ensure your data remains private.
