Online Number Exclusion Filter

What this tool actually does

Removes any parsed number whose normalized JavaScript string contains at least one selected digit. The exclusion field keeps only characters 0 through 9 and must contain at least one digit; commas, spaces and other separators in that field are ignored.

Checkable behavior

Verified values 12, 34, 56 with excluded digits 2 and 5 return only 34. Multiple selected digits use OR logic: a value is removed when any selected digit occurs. Original list order and repeated retained values are preserved.

Controls, output and limitations

Matching uses String(number) after numeric parsing, not the original text. Leading zeros and plus signs disappear, scientific notation may normalize, and locale decimal punctuation is not part of the digit test. A minus sign and decimal point are never selected characters.

Source input follows the regional number parser and is limited to 100,000 characters and 10,000 finite values. Output is formatted for the page locale. The tool does not exclude numeric ranges, positions, repeated-digit counts or exact text substrings.

The operation runs locally without uploading values. Use a text filter for account codes, phone numbers or identifiers where leading zeros and original character representation are meaningful.
