Increase a Number

Increase a Number lets you quickly add a specific amount to every number in your input. Whether you’re offsetting values, running math transformations, or prepping numeric data, this tool handles it instantly with live updates.

How to Use:

1. Paste numbers into the Input Numbers box, one per line.
2. Or import a .txt, .csv, or .log file using the Choose File button.
3. In the Options box:
   • Set the amount to add using the Increase by field.
   • Enable Trim whitespace to clean messy input.
4. The output updates live as you type or import.
5. Use Copy Output or Export to File to save your results.
6. Click Clear All to reset everything and start over.

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

Number Increase Table:

This table shows how input values change when a constant amount is added to each one. It’s useful for adjusting scores, offsetting raw data, or prepping numeric lists for further processing.

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.
