What Convert CSV Rows to an Array can do:

This tool transforms tabular CSV into structured JSON either as a list of arrays or a list of objects using headers as keys. It’s ideal for converting spreadsheet data into formats usable in JavaScript, APIs, or config files. You can trim spaces, quote fields, and toggle between raw arrays or key-value objects. The output is easy to read and ready to paste or save. Everything runs locally in your browser, so it’s fast and secure.

Example:

CSV Input:

name,age,city
Alice,30,New York
Bob,25,Los Angeles

JSON Output (objects):

[
  { "name": "Alice", "age": 30, "city": "New York" },
  { "name": "Bob", "age": 25, "city": "Los Angeles" }
]

Or (raw array mode):

[
  ["name", "age", "city"],
  ["Alice", "30", "New York"],
  ["Bob", "25", "Los Angeles"]
]

Common Use Cases:

Use this to convert spreadsheet exports into structured JSON for development, automation, static config files, or templating. It’s especially helpful for web developers, data handlers, or anyone bridging between CSV and JavaScript.

Useful Tools & Suggestions:

After conversion, Convert an Array of Arrays to CSV lets you flip it right back if needed. And if you’re working with subsets of data, Slice CSV can help you isolate just the rows you want to convert.
