## About

CSV is the lingua franca of spreadsheets; JSON is the language of APIs. Moving data between the two is a daily task for developers, analysts, and marketers alike.

This converter parses your CSV into clean JSON objects using the header row as keys — or flattens a JSON array back into a spreadsheet-ready CSV. Quoted fields, embedded commas, and newlines are all handled correctly, and nothing leaves your browser.

## How to use

1. **Paste your CSV** — The first row is treated as column headers. Semicolon and tab delimiters are detected automatically.
2. **Switch direction** — Toggle to "JSON to CSV" and paste a JSON array of objects to get a CSV back.
3. **Copy the result** — Use the copy button to grab the converted output in one click.

## Examples

### A simple contacts list

CSV with headers becomes an array of objects.

Input:

```
name,email
Ada,ada@example.com
Grace,grace@example.com
```

Output:

```
[{"name":"Ada","email":"ada@example.com"},{"name":"Grace","email":"grace@example.com"}]
```

## FAQ

### Does it handle quoted fields with commas?

Yes. Fields wrapped in double quotes can contain commas, newlines, and escaped quotes, and the parser keeps them intact.

### What if my CSV uses semicolons?

The delimiter is detected automatically from the first line. You can also switch it manually between comma, semicolon, and tab.

### Is my data uploaded to a server?

No. Conversion happens locally in your browser, so sensitive data never leaves your device.
