How to merge json files

Suppose you have two JSON files that you need to merge:

file_01

{
  "persons": [
    {
      "name": "Maria",
      "age": 30,
      "car": null
    }
  ]
}

file_02

{
  "persons": [
    {
      "name": "Jon",
      "age": 30,
      "car": null
    }
  ]
}

Our tool will attempt to merge them by checking if they have similar main titles (like "persons" in this case). If they do, it will concatenate the data under those titles. The rest of the content will also be concatenated if necessary, ensuring all data is unified without losing information.

{
  "persons": [
    {
      "name": "Maria",
      "age": 30,
      "car": null
    },
    {
      "name": "Jon",
      "age": 30,
      "car": null
    }
  ]
}

Our JSON File Merger is a developer tool designed to simplify the process of merging multiple JSON files. It automatically searches for all matching keys in the files and concatenates the associated data, ensuring seamless merging without overwriting any information.

Whether you're working with API data, database data, or data from different sources, this tool helps you effectively merge JSON files. It's ideal for developers and data managers looking for a simple solution to unify their data into a single structure.
