Frequently asked questions
How does this tool split my text into an array?
Every line becomes one string element in the resulting JSON array, in the same order as your input.
Are empty trailing lines included?
No — trailing blank lines at the end of the input are trimmed automatically so you don't get empty strings in the output.
What's a common use case for this?
Turning a plain list — like a list of names, tags, or file paths — into a JSON array you can paste into code or an API request.
