## Overview

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.

## Inputs

- **Text Input** (textarea): Enter text to slice...
- **Start Index** (number): Enter start index...
- **End Index** (number): Enter end index (leave empty for end)...
- **Slice Mode** (select)
- **Apply to Each Line** (checkbox)

## When to use

- When you need to extract specific character ranges from long strings or log files.
- When you want to clean up structured data by removing prefixes or suffixes.
- When you need to apply the same character extraction rule across multiple lines of text at once.

## How it works

- Paste your source text into the input field.
- Define your start and end indices to specify the desired range.
- Select your preferred slice mode to handle index logic, such as negative indexing or standard substring normalization.
- Toggle 'Apply to Each Line' if you need to process a list of items simultaneously.

## Use cases

- Extracting specific ID codes from a list of formatted serial numbers.
- Removing unwanted header or footer characters from bulk data exports.
- Isolating specific date or time segments from standardized log entries.

## Frequently asked questions

### What is the difference between Slice and Substring modes?

Slice mode supports negative indices (counting from the end of the string), while Substring mode normalizes negative indices to zero.

### Can I extract text from every line in a document?

Yes, enable the 'Apply to Each Line' option to run your specified index range against every line in your input.

### What happens if I leave the end index empty?

The tool will automatically extract the text from your start index until the very end of the string.

### Does this tool support multi-line input?

Yes, you can paste large blocks of text, and the tool will process them according to your selected mode.

### Are the indices zero-based?

Yes, the tool uses zero-based indexing, meaning the first character of your text is at index 0.
