Frequently Asked Questions

Find Quick Answers

What is the maximum range I can generate?

The tool can handle large ranges, but for performance, it's recommended to keep it under 1,000,000 numbers. Extremely large lists may slow down your browser.

Can I use decimal numbers?

Yes, you can use decimal values for start, end, and step (e.g., 1.5 to 5.0 with step 0.5). The tool supports floating-point numbers.

What does 'Padded with Zeros' format do?

This format adds leading zeros to numbers so they all have the same digit count (e.g., 001, 002, 003 for a range 1-3). It's useful for sorting or file naming.

Is my data stored or sent to a server?

No, all processing happens locally in your browser. Your number sequences are never transmitted or stored externally, ensuring complete privacy.
