What Convert Integers to Unary Base can do:

This tool converts each integer into a unary string a line of vertical bars equal to the number’s value. For example, 5 becomes ||||| and 0 becomes an empty line. It ignores negative values by default, unless you turn off filtering.

It’s great for symbolic math, visual counting systems, or just messing with alternate number bases. It runs entirely in your browser, fast and private.

Example:

Input:

3
5
apple
0
5

Output (with ignore + dedupe on):

|||
|||||

Common Use Cases:

Perfect for illustrating number representations in education, generating test data for unary-based puzzles, or even visualizing counts without digits. You can paste hundreds of values and get clean, line-by-line unary output in seconds.
