Rewrite Numbers

Rewrite Numbers takes your list of values and instantly reformats them the way you want.

What Rewrite Numbers can do:

This tool lets you reformat numbers line-by-line in the way that fits your needs. If you’re working with big data, Comma Format gives you nicely separated thousands. Scientific Notation keeps your large or tiny values compact and readable. And the Words option uses standard digit string output great for clean input normalization.

The Options box adds more control. “Trim whitespace” ensures that stray spaces don’t cause parse errors. If you enable “Ignore empty lines,” the tool skips over blank rows completely, keeping your output neat. The mode you choose with the radio buttons determines how each line will be transformed. These settings work together, giving you flexibility without adding clutter.

Example:

Input:

1234
56.78
9000
0.25

Output (Comma Format):

1234 → 1,234
56.78 → 56.78
9000 → 9,000
0.25 → 0.25

Common Use Cases:

Rewrite Numbers is great when you’re cleaning up raw datasets, formatting values for display, or converting reports for easier reading. You can use it in financial exports, lab reports, dashboards anywhere numbers need to look better or make more sense fast.

Useful Tools & Suggestions:

If you’re rewriting numbers, Replace Digits with Letters can twist things even further great for puzzles or obfuscation. And when you’re ready to shuffle things up, Sort Digits in a Number gives you a quick way to reorder without changing the core value too much.
