ArrayCat

What is ArrayCat?

ArrayCat is a free browser tool that turns any text or data list into arrays for PHP, JavaScript, Python, SQL and more. Just paste your text or upload a CSV, choose an output format, and watch your lists transform into clean, ready-to-use arrays. You can also sort items, remove duplicates, strip diacritics, convert to lowercase, encode to base64, fix quotes, and convert characters to HTML entities. All processing happens locally in your browser, so your data stays private.
