If you work with JSON data, you may often need to merge JSON files into a single file. This is useful for better organization or processing. Whether you're a developer, data analyst, or just someone handling multiple JSON files, merging them efficiently can save you time and effort. It helps streamline your workflow and makes your data easier to manage.

Why Merge JSON Files?

There are several key reasons why merging JSON files is beneficial:

• Combining JSON files helps consolidate data from multiple sources. This is especially helpful when dealing with data coming from different systems.
• It simplifies data analysis and processing. A single file is much easier to work with than multiple files.
• Reduces redundancy by keeping data in a single structured format. This prevents data duplication and ensures consistency.
• Improves data management. A single file is easier to back up, share, and manage.

Merging JSON Files In Different Languages

For developers, here’s how to merge JSON files using different programming languages:

Merge JSON Files In Python

import json

files = ['file1.json', 'file2.json']
merged_data = []

for file in files:
    with open(file) as f:
        merged_data.extend(json.load(f))

with open('merged.json', 'w') as f:
    json.dump(merged_data, f, indent=4)

This Python code reads data from multiple JSON files, combines it into a single list, and then writes the combined data to a new JSON file.

Merge JSON Files In JavaScript

const fs = require('fs');

const files = ['file1.json', 'file2.json'];
let mergedData = [];

files.forEach(file => {
    const data = JSON.parse(fs.readFileSync(file));
    mergedData = mergedData.concat(data);
});

fs.writeFileSync('merged.json', JSON.stringify(mergedData, null, 2));

This JavaScript code performs a similar function to the Python code, reading and merging JSON data from multiple files.

Bash (Using jq) Merge JSON Files

jq -s 'add' file1.json file2.json > merged.json

This Bash command uses the `jq` command-line JSON processor to efficiently merge the files.
