JSON & CSV Converter & Viewer

JSON CSV Master is an essential data processing tool for developers, data analysts, and students. It allows you to visualize complex and hard-to-read JSON and CSV data in an intuitive table format and easily convert it to your desired format with powerful features.

Key Features

1. Clean Data Visualization
* Displays JSON arrays and CSV files in an intuitive table format, allowing you to understand the data structure at a glance.
* **Preserves JSON Key Order**: Displays columns in the exact order they appear in your JSON file.
* JSON data that is difficult to represent in a table (e.g., JSON starting with an object) can be viewed directly using the **Open in Text Editor** feature.

2. Powerful and Flexible Conversion
* JSON ↔ CSV Mutual Conversion: Convert JSON to CSV, or CSV to JSON, with just a few taps.
* Handling Nested JSON: Provides two advanced options for converting complex nested JSON structures.
* **Flatten with dots**: Flattens nested structures like {"user": {"name": "John"}} into a header connected by dots, such as user.name, representing all data as columns in the CSV.
* **Keep objects as strings**: Preserves nested JSON objects or arrays as-is in string format within their cells, maintaining the original data structure as much as possible during conversion.

3. Convenient Editing and Saving
* Both the original data (JSON/CSV) and the converted results can be opened and modified directly in the built-in **Text Editor**.
* **Prettify Support**: Offers a formatting feature to make large, single-line (minified) JSON files easy to read.
* Edited content can be saved as a new file, enhancing the efficiency of data preprocessing and management tasks.

4. Support for Various Input Methods
* Open File: Directly open and work with .json or .csv files stored on your device.
* Paste from Clipboard: Quickly check data by pasting JSON/CSV data copied from the web or other apps directly from the clipboard.
* Sample Data Provided: Includes various sample files to let you test the app's main features immediately.
