Tool usage guide
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.
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.
inputFormat: json, keyCase: camel, outputFormat: jsonOutcome
A clean, standardized JSON object with all keys converted to camelCase.
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.
The tool supports JSON objects, raw JavaScript objects, and standard key-value pairs.
Yes, you can transform keys into lowercase, UPPERCASE, camelCase, snake_case, kebab-case, or PascalCase.
Yes, you can select 'Environment Variables' as the output format to generate key=value strings suitable for .env files.
Yes, you can sort the output by keys or values in either ascending or descending order.
No, all processing is performed locally in your browser to ensure your data remains private.
inputFormat: json, outputFormat: env, separator: =Outcome
A formatted string ready to be saved directly into a .env file.
