How to use Convert CSV Rows to an Array
- 1. Paste your CSV. Drop the comma-separated rows into the input pane. The chosen rows are collected into a JSON array with each field kept in its original order.
- 2. Choose which rows to extract. Enter 1-based row numbers in the Rows field, separated by commas, or leave it empty to convert every row's values into their own array.
- 3. Decide how values are typed. Turn on Convert numbers and booleans to store digit-only fields as real JSON numbers and true/false text as booleans, instead of leaving every value as a quoted string.
- 4. Copy the JSON array. Copy the resulting array of values and paste it into a script, a test fixture, or anywhere a specific row's data needs to be represented as JSON rather than CSV.
When to use Convert CSV Rows to an Array
Convert CSV Rows to an Array pulls a specific row's fields out of a CSV and formats them as a JSON array, ready to paste straight into code. It targets one record at a time rather than the whole table.
- Building a single test case from sample data. A test suite needs one row of a CSV represented as a JSON array of arguments. Extracting that row directly saves manually retyping each field with correct quoting and types.
- Passing a record into a function call. You're debugging a function that expects an array of positional values, and the sample data lives in a spreadsheet row. Extracting it saves manual transcription errors.
- Documenting an example record in code comments. A code comment illustrates the expected shape of a data row using a JSON array. Extracting a real row from your CSV keeps the example accurate and up to date.

About the Convert CSV Rows to an Array tool
Convert CSV Rows to an Array does its work locally, right in the browser. Create an array from one or more CSV rows. There is no upload step, no queue and no account, and your data never travels over the network.
It belongs to the CSV Tools collection on EditSafely, a set of 133 small, focused CSV utilities that share the same instant, private workspace.
You can shape the output with 2 settings, including Rows (1-based numbers, empty = all) and Convert numbers and booleans, and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
Running locally also makes the tool fast and dependable: results appear as you type or drop a file, there is no server outage that can take it down mid-task, and confidential data can be processed without a second thought.
Frequently asked questions
Is Convert CSV Rows to an Array free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
