Frequently Asked Questions

What can I convert to an array?

Paste a list of items—one per line—and the tool converts it to a JSON array. You can choose different quote styles: double quotes, single quotes, or no quotes.

What are the quote style options?

Double quotes produce standard JSON (e.g., ["a","b"]). Single quotes and no quotes are useful when you need the output in a specific format for other tools or templates.

Can I remove duplicates from my list?

Yes! The tool can deduplicate your list, keeping only unique items. Useful when merging lists or cleaning up data.

What about sum and average?

If your list contains numbers, the tool can calculate the sum and average of those values—handy for quick data analysis.
