# Diff nested JSON, API responses, and config snapshots before approving changes

> Uses DeepDiff to compare structured objects deeply and return precise additions, removals, value changes, and deltas instead of noisy line-based diffs. Best when an agent is validating API payloads, configuration snapshots, or migration outputs where nesting and key paths matter.

# Diff nested JSON, API responses, and config snapshots before approving changes

Uses DeepDiff to compare structured objects deeply and return precise additions, removals, value changes, and deltas instead of noisy line-based diffs. Best when an agent is validating API payloads, configuration snapshots, or migration outputs where nesting and key paths matter.

## Installation

Use the upstream install or setup path that matches your environment:
- pip install deepdiff
- pip install "deepdiff[cli]"
- pip install "deepdiff[optimize]"
- Method 2: Use pip: pip install -e ".[cli,coverage,dev,docs,static,test]"

Requirements and caveats from upstream:
- ![Python Versions](https://img.shields.io/pypi/pyversions/deepdiff.svg?style=flat)
- [Extract](https://zepworks.com/deepdiff/current/extract.html): Extract an item from a nested Python object using its path.
- Tested on Python 3.10+ and PyPy3.

Basic usage or getting-started notes:
- If you want to use DeepDiff from commandline:
- If you want to improve the performance of DeepDiff with certain functionalities such as improved json serialization:
- [yaml](https://pypi.org/project/PyYAML/)
