Introduction to the tool and how to use it
The Digit Exclusion Filter picks out numbers that contain (or do not contain) certain digits, for example removing every code with a 4 or keeping only numbers whose last digit is 8.
Note: matching ignores the sign and decimal point; a position beyond the number's length never matches.

How to use
- Paste the numbers into the input box; commas, spaces, line breaks, or any symbol may be used as separators.
- Enter the digits to exclude; you may enter several (for example 4,7; only 0-9 are recognized, other characters are ignored automatically).
- Choose the matching position: any digit means a match if the number contains these digits anywhere; specific position means checking only the digit at the given place counted from the right (1 = units).
- Choose the action: remove numbers containing these digits, or keep only those containing them.
- Click start; the text box on the right prints results separated by the separator, and the table below lists each match as index / number / matched digits (copy in place), with CSV download available.
