Compare JSON Documents Leave feedback

GroupDocs.Comparison for Python via .NET compares JSON files and detects differences in nested objects, arrays, data types, and structures. This is useful for validating APIs, configurations, and large datasets where accuracy is critical.

The API can:

• Compare two or more JSON documents.
• Highlight differences in nested objects, arrays, and values.
• Produce a visual HTML report with highlighted differences, or a textual merged JSON file with inline diff markers.
• Accept or reject detected changes programmatically.

from groupdocs.comparison import Comparer

def compare_json_documents():
    with Comparer("./source.json") as comparer:
        comparer.add("./target.json")
        comparer.compare("./result.json")

if __name__ == "__main__":
    compare_json_documents()

result.html (635 bytes)
result.json (170 bytes)

The resulting result.json contains the combined JSON structure with differences highlighted inline.

Generate a single HTML report that highlights changes visually — deletions in red, insertions or modifications in blue. Add a summary page that lists every change.

from groupdocs.comparison import Comparer
from groupdocs.comparison.options import CompareOptions

def compare_json_to_html():
    options = CompareOptions()
    options.generate_summary_page = True

    with Comparer("./source.json") as comparer:
        comparer.add("./target.json")
        comparer.compare("./result.html", options)

if __name__ == "__main__":
    compare_json_to_html()

Produce a merged JSON file with inline diff markers; detect style and deletion changes.

from groupdocs.comparison import Comparer
from groupdocs.comparison.options import CompareOptions

def compare_json_textual():
    options = CompareOptions()
    options.detect_style_changes = True
    options.show_deleted_content = True

    with Comparer("./source.json") as comparer:
        comparer.add("./target.json")
        comparer.compare("./result.json", options)

if __name__ == "__main__":
    compare_json_textual()

result.html (635 bytes)
result.json (170 bytes)

generate_summary_page = True appends a high-level change-count summary to any output format. detect_style_changes = True ensures structural / type-level changes in JSON (e.g., a string becoming a number) are surfaced explicitly.

• Accept or reject detected changes — applies to JSON comparison results as well.
• Get list of changes — read the raw change list to build a custom diff UI.
• Adjusting comparison sensitivity — tune how aggressively small JSON edits are reported.
