What Count Number Occurrences can do:

This tool reads through your entire input and finds every number. It counts how many times each unique number appears, then shows the totals in either numeric or frequency order. Zeros can be ignored with one click, and everything updates live as you go.

A line counter shows the number of unique items found. You can copy the output or export it for use elsewhere.

Example:

Input:

5 2 5 3 5 2 4 3 1 5 2 2

Output:

1: 1
2: 4
3: 2
4: 1
5: 4

Common Use Cases:

Use this tool for numeric analysis, repetition checking, statistics generation, and even debugging data exports. It’s a quick way to get insight into what numbers show up most without needing formulas or spreadsheets.
