How to use Split a String into a JSON Array
- 1. Paste your text. Put the plain text you want turned into a JSON array into the input pane. It can be a single line, a paragraph, or a multi-line list.
- 2. Choose how to split it. Pick Words, Lines or Characters for the common cases, or Custom to split on a delimiter you type into the Custom delimiter field, such as a comma or a semicolon.
- 3. Decide on empty entries. Turn on Skip empty entries to drop blank results caused by consecutive delimiters, such as double commas or trailing newlines, so the array only holds real content.
- 4. Copy the resulting array. Choose an Indent, then copy the JSON array and paste it into a script, config file or test case that needs the text as structured data.
When to use Split a String into a JSON Array
Split a String into a JSON Array turns plain text into a JSON array by breaking it apart on words, lines, characters or a delimiter you choose. It is for the moment a list exists as loose text but the next step in your workflow needs it as structured JSON.
- Converting a spreadsheet column into an array. You copied a comma-separated list of tags out of a spreadsheet cell and need it as a proper JSON array for a config file or an API request body.
- Turning a list of emails into structured data. You have a multi-line list of email addresses pasted from an invite list and need each one as a separate array entry to send to an API endpoint.
- Tokenizing a sentence for an NLP test. A natural language processing test needs a sentence split into individual word tokens as a JSON array, rather than a single string it would have to split itself.
- Building an array from raw CSV text. A single CSV column pasted as plain text needs to become a JSON array of values before it can be imported into a JavaScript application.
Examples
Split a sentence into words
Input
grace loves math
Output
[ "grace", "loves", "math" ]

Frequently asked questions
Is Split a String into a JSON 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.
