- How to Use
- Paste the minified API response into the JSON Input field and set the indent size to 2.
- Example Config
-
indentSize: 2 - Outcome
- The JSON was instantly expanded into a readable, hierarchical format, allowing the developer to locate the error in seconds.
2. Standardizing Config Files
DevOps Engineer- Background
- A team member committed a configuration file that lacked consistent indentation, making it difficult to review in pull requests.
- Problem
- The file needed to be reformatted to follow the team's style guide before being merged.
- How to Use
- Copy the raw configuration content, paste it into the tool, and apply a 4-space indentation.
- Example Config
-
indentSize: 4 - Outcome
- The configuration file was perfectly aligned, ensuring clean version control history and easier peer reviews.
