CSV Exporter Utility

Description

CSV Exporter Utility is a simple, yet powerful package that allows you to easily convert a JSON array of data into a CSV file and download it in a user-friendly way. This utility is highly useful when you need to export data from a web application or API to a CSV file format, which can then be imported into other tools or processed further.

Why use CSV Exporter Utility

• Easy to integrate into your existing projects
• Lightweight with no external dependencies
• Handles complex JSON data structures and nested objects
• Automatically generates CSV headers from JSON keys
• Allows omission of specific properties from the CSV export
• Supports nested properties omission with dot notation
• Cross-browser compatibility
• User-friendly file download experience

How to use CSV Exporter Utility

1. Install the package using npm or yarn:

npm install csv-exporter-utility

2. Import the downloadCSVFile function from the package:

import { downloadCSVFile } from "csv-exporter-utility";

3. Use the downloadCSVFile function in your application to convert and download JSON data as a CSV file. You can also pass an array of property names to omit certain fields from the CSV:

const jsonData = [
  { id: 1, name: "John Doe", email: "[email protected]" },
  { id: 2, name: "Jane Doe", email: "[email protected]" },
];

// Omit the "email" field from the CSV
downloadCSVFile(jsonData, "users", ["email"]);

In the above example, the email field is omitted from the downloaded users.csv file.

Additional support: Dot notation for nested properties

You can also omit nested properties using dot notation:

// Omit the "user.age" field from the CSV
downloadCSVFile(jsonData, "users", ["user.age"]);

This will omit the age field inside the user object, allowing more control over complex JSON data structures.

• Export data from your web application to a CSV file
• Provide users with a simple way to download data in a structured format
• Convert JSON data to CSV for further processing or analysis
