Tool usage guide
Text Slicer is a precise utility designed to extract specific segments from your text data by defining start and end indices. Whether you need to isolate a character range or process multiple lines of text simultaneously, this tool provides a clean, efficient way to manipulate strings without manual editing.
Background
A list of product codes contains a prefix that needs to be removed for database entry.
Problem
The first 4 characters of every line are unnecessary prefixes.
How to use
Paste the list, set Start Index to 4, leave End Index empty, and enable 'Apply to Each Line'.
startIndex: 4, sliceMode: 'slice', perLine: trueOutcome
The tool returns a clean list of serial numbers with the prefixes removed.
Background
Need to extract the last 3 characters from a list of filenames to identify file types.
Problem
Manually identifying extensions for hundreds of files is inefficient.
How to use
Paste the filenames, set Start Index to -3, and enable 'Apply to Each Line'.
startIndex: -3, sliceMode: 'slice', perLine: trueSlice mode supports negative indices (counting from the end of the string), while Substring mode normalizes negative indices to zero.
Yes, enable the 'Apply to Each Line' option to run your specified index range against every line in your input.
The tool will automatically extract the text from your start index until the very end of the string.
Yes, you can paste large blocks of text, and the tool will process them according to your selected mode.
Yes, the tool uses zero-based indexing, meaning the first character of your text is at index 0.
Outcome
A list containing only the 3-character file extensions for each entry.
