What Increase a Number can do:

The tool parses each line and tries to convert it to a number. If it succeeds, it adds your custom amount and outputs the new value. If it encounters a non-number line, it leaves it unchanged making it safe for mixed input.

You can also adjust decimal-based increments (like 0.25) and use file input to process large batches at once. The result flashes live in the output pane, and a counter shows how many lines were handled.

Example:

Input:

7
42
908

Settings: Increase by: 5, Trim whitespace: ON

Output:

12
47
913

Common Use Cases:

Use this when batch-increasing values for scores, offsets, versioning, or numeric tracking. It’s ideal for developers, spreadsheet users, and anyone needing a quick numeric adjustment no formulas required.

Useful Tools & Suggestions:

If you’re stepping values up, Decrease a Number works the same way in reverse when you need to scale things down. And for more unpredictable adjustments, Add Errors to Numbers lets you shift values by percentage or fixed amounts.
