Overview
Introduction
Removing every instance of a particular digit from a batch of hex values by hand is tedious and error-prone, especially across a long list where the digit might appear anywhere in each value.
This tool strips every occurrence of a chosen digit character out of every value in a list of hex values in one pass, leaving all the other digits exactly where they were.
What Is Hex Digit Remover?
The Hex Digit Remover takes a single digit character and deletes every matching occurrence of it from each value in your input list, shortening any value that contained it.
Matching is case-insensitive, so it doesn't matter whether the digit you type or the digits in your input use upper or lower case letters.
How Hex Digit Remover Works
The digit to remove is validated as a single hex character (0-9 or A-F); anything else is rejected with a clear error before any removal happens.
Each value in the parsed input list has every occurrence of that digit deleted using a split-and-join operation, and the (possibly shortened) results are joined back into a list, one value per line.
When To Use Hex Digit Remover
Use this to strip a specific digit out of a whole batch of values at once, for example removing a padding character, a known-bad digit, or a placeholder character that was accidentally embedded in your data.
It's also useful for quick experimentation, seeing what a value looks like with one particular digit removed entirely.
Often used alongside Hex Digit Replacer, Hex Digit Sorter and Hex Value Truncator.
Features
Advantages
- Removes every occurrence of the target digit across the whole list in a single operation.
- Case-insensitive matching means the digit's letter casing in your input doesn't matter.
- Leaves every other digit in every value completely untouched.
Limitations
- Removes exactly one digit type per run; stripping multiple digit types requires running the tool again on its own output.
- Removal is lossy and changes a value's numeric meaning (and length); it is not a value-preserving operation.
Examples
Best Practices & Notes
Best Practices
- Double-check the digit field holds exactly one character; anything else is rejected with an error.
- If a value could become empty after removal, expect an empty output line for it rather than the line disappearing entirely.
Developer Notes
Removal is implemented as `value.split(target).join("")` on each already-uppercased value, which deletes every occurrence of the target character in one pass, including the edge case of a value made entirely of that character, which correctly reduces to an empty string.
Hex Digit Remover Use Cases
- Stripping a known placeholder or padding digit out of a batch of hex values
- Removing an erroneous digit that was mistakenly embedded across many values
- Exploring how a value looks, and what it numerically becomes, with a specific digit removed
Common Mistakes
- Entering more than one character in the digit field; it must be exactly one hex digit.
- Assuming a value that becomes empty after removal is simply dropped from the output; it's kept as an empty line instead.
Tips
- To swap a digit for another instead of deleting it, use Hex Digit Replacer.
- Chain multiple removal passes (one digit at a time) by feeding this tool's output back into itself for a different target digit.
