Random Array Generator

Generates a JSON array with an integer length from 1 to 1000; the default is 10 integers. Integer elements range from −1000 to 1000. Strings contain 4–10 lowercase ASCII letters a–z, and Boolean elements are true or false. Mixed mode chooses one of these three types for each position; it need not include every type.

Values and complete arrays may repeat. There are no custom ranges, uniqueness settings or configurable seeds. Generate explicitly after changing length or type: editing or pressing Enter leaves the previous result in place. Copy the displayed JSON to reuse it; there is no file download or visible example button. Clear removes the result and keeps length and type. Generation runs locally after page resources load; offline page availability is not guaranteed.
