Merge multiple JSON files

Merging multiple JSON files typically involves reading all the JSON files, combining their contents into a single structure (like an array or an object), and then outputting the merged result. The exact merging logic depends on the structure of the JSON files and what you want the final output to look like.

Here’s a general approach with an example in Python:

python
CopyEdit
import json
import glob

# List all JSON files in a directory (adjust the path accordingly)
json_files = glob.glob('path/to/json/files/*.json')

merged_data = []

for file in json_files:
    with open(file, 'r', encoding='utf-8') as f:
        data = json.load(f)
        # Assuming each file contains a JSON array; adjust if it's an object
        if isinstance(data, list):
            merged_data.extend(data)
        else:
            merged_data.append(data)

# Save merged result
with open('merged.json', 'w', encoding='utf-8') as f:
    json.dump(merged_data, f, indent=4)

Explanation:

• The script collects all JSON files in a folder.

• It loads each JSON file, assuming each file contains either a JSON array or an object.

• If the content is a list, it extends the merged list; otherwise, it appends the object.

• Finally, it writes the merged content to a new JSON file.
