When working with APIs, software projects, or data-heavy applications, JSON (JavaScript Object Notation) is the standard format for storing and sharing information. But what happens when you need to compare two versions of JSON files to spot the differences?
That’s where the Diff JSON Tool from One Code Studio comes in. This lightweight, browser-based tool makes it easy to quickly identify changes, additions, or errors between two sets of JSON data.
What Is the Diff JSON Tool?
The Diff JSON Tool helps developers, testers, and data analysts compare two JSON inputs side by side. It highlights what’s different between them so you don’t have to manually scan through hundreds of lines of code.
You can use it for:
- Debugging API responses
- Spotting differences between old and new configurations
- Verifying data migrations
- Ensuring consistency between test and production environments
