Compare JSON documents Leave feedback
On this page
GroupDocs.Comparison for Python via .NET allows developers to easily compare JSON files and detect differences in deeply nested objects, arrays, data types, and structures.
This is useful for validating APIs, configurations, and large datasets where accuracy is critical.
With the API, you can:
- Compare two or more JSON documents\
- Highlight differences in nested objects, arrays, and values\
- Use visual mode (HTML report with highlights) or textual mode (JSON diff output)\
- Apply or reject detected changes programmatically
import groupdocs.comparison as gc
source_path = "source.json"
target_path = "target.json"
result_path = "result.json"
# Initialize the comparer with the source JSON document
with gc.Comparer(source_path) as comparer:
# Add the target JSON document
comparer.add(target_path)
# Compare and save the result file
comparer.compare(result_path)
The resulting result.json will contain the combined JSON structure with differences highlighted inline.
Generate a single HTML report that highlights changes visually:\
- Deleted items appear in red\
- Inserted or modified items appear in blue
import groupdocs.comparison as gc
from groupdocs.comparison.options import CompareOptions
source_path = "source.json"
target_path = "target.json"
result_path = "result.html"
options = CompareOptions()
options.generate_summary_page = True # Include summary of changes
with gc.Comparer(source_path) as comparer:
comparer.add(target_path)
comparer.compare(result_path, options)
Produce a merged JSON file with inline diff markers:\
- Deleted content is wrapped in
[ ]\ - Inserted content is wrapped in
( )
import groupdocs.comparison as gc
from groupdocs.comparison.options import CompareOptions
source_path = "source.json"
target_path = "target.json"
result_path = "result.json"
options = CompareOptions()
options.detect_style_changes = True
options.show_deleted_content = True
with gc.Comparer(source_path) as comparer:
comparer.add(target_path)
comparer.compare(result_path, options)
You can also programmatically accept or reject detected changes in JSON comparison results:
import groupdocs.comparison as gc
source_path = "source.json"
target_path = "target.json"
result_path = "result.json"
with gc.Comparer(source_path) as comparer:
comparer.add(target_path)
# Run comparison first
comparer.compare(result_path)
# Iterate over detected changes
for change in comparer.get_changes():
if change.comparison_action == "Deleted":
change.comparison_action = "Reject" # reject deletion
else:
change.comparison_action = "Accept" # accept additions/updates
# Apply the updated decisions
comparer.apply_changes(result_path)
