String Splitter
Split text by custom delimiter into separate lines or array instantly. Customize separator, trim whitespace, remove empty entries, and process CSV data, lists, or any delimited text with flexible options.
String Splitter Tool Introduction
A versatile string splitter that divides text into separate lines or entries based on custom delimiters. Essential for processing CSV data, converting formats, organizing text content, parsing lists, and transforming delimited data into structured formats.
Perfect for developers, data analysts, content managers, and anyone working with delimited text data. The tool provides flexible options including whitespace trimming, empty entry removal, and support for any custom delimiter including special characters.
Our splitter handles complex scenarios including multi-character delimiters, special characters, and various text formats. Whether you're processing comma-separated values, space-delimited lists, or custom-formatted data, this tool streamlines your text processing workflow.
All processing happens locally in your browser with no data transmission. Your text data remains completely private and secure.
String Splitter User Guide
Getting Started
Using the String Splitter is simple and powerful:
Basic Usage
- Enter Text: Paste or type the text you want to split
- Set Delimiter: Enter the separator character or string
- Configure Options: Enable trim whitespace or remove empty entries
- Split: Click to process and split the text
- Copy Result: Copy the split results for use elsewhere
Common Delimiters
Standard Separators
- Comma (,): CSV files, lists, data exports
- Space ( ): Word lists, simple data
- Tab (\t): TSV files, tabular data
- Semicolon (;): European CSV format, alternative separator
- Pipe (|): Database exports, structured data
Line Breaks
- Newline (\n): Split by lines (already line-separated text)
- Paragraph breaks: Double newlines for paragraph splitting
Custom Delimiters
- Multi-character: Use any string like " - ", " :: ", or custom patterns
- Special characters: Colon (:), slash (/), dash (-), etc.
- Custom text: Any specific text pattern you need
Processing Options
Trim Whitespace
Removes leading and trailing spaces from each split item:
- Before: " apple ", " banana ", " cherry "
- After: "apple", "banana", "cherry"
- Use when: Data has inconsistent spacing
Remove Empty Entries
Filters out empty strings from the result:
- Before: "apple", "", "banana", "", "cherry"
- After: "apple", "banana", "cherry"
- Use when: Data has consecutive delimiters or trailing separators
Common Use Cases
Data Processing
- CSV Parsing: Split comma-separated values into individual items
- TSV Processing: Parse tab-separated data
- Database Exports: Split pipe-delimited or custom-delimited data
- Log Analysis: Parse structured log entries
List Management
- Email Lists: Split comma or semicolon-separated email addresses
- Tag Processing: Parse comma-separated tags or keywords
- Name Lists: Split lists of names or items
- URL Lists: Parse lists of URLs or paths
Text Formatting
- Sentence Splitting: Split by periods or other punctuation
- Word Extraction: Split by spaces to get individual words
- Paragraph Parsing: Split by double newlines
- Custom Format Conversion: Transform delimited text to line-separated
Development Tasks
- Array Creation: Convert delimited strings to array format
- Config Parsing: Split configuration values
- Path Processing: Split file paths or URLs
- Data Transformation: Convert between different delimiter formats
Examples
Example 1: CSV Data
Input: apple,banana,cherry,date
Delimiter: ,
Result:
- apple
- banana
- cherry
- date
Example 2: Space-Separated with Trimming
Input: apple banana cherry
Delimiter: (space)
Options: Trim whitespace ✓, Remove empty ✓
Result:
- apple
- banana
- cherry
Example 3: Custom Multi-Character Delimiter
Input: apple :: banana :: cherry
Delimiter: ::
Result:
- apple
- banana
- cherry
Best Practices
Choosing Delimiters
- Match Source Format: Use the delimiter that exists in your data
- Avoid Ambiguity: Choose delimiters that don't appear in your data
- Consider Standards: Use comma for CSV, tab for TSV
- Test First: Try with a small sample before processing large data
Using Options Effectively
- Always Trim: Enable for cleaner results in most cases
- Remove Empty: Enable when data has inconsistent delimiters
- Keep Empty: Disable when empty values are meaningful
- Preview Results: Check the count to verify splitting worked correctly
Data Quality
- Check for unexpected delimiters in your data
- Verify the split count matches expectations
- Review results for any anomalies
- Consider escaping if delimiter appears in data values
Key Features
- Custom Delimiters: Use any character or string as separator
- Whitespace Trimming: Clean up spacing automatically
- Empty Removal: Filter out blank entries
- Item Count: See how many items were created
- Numbered Output: Results shown with line numbers
- One-Click Copy: Copy all results easily
- No Length Limit: Process text of any size
- Privacy Protected: All processing happens locally
Tips & Tricks
- Use multi-character delimiters for complex data formats
- Enable both trim and remove empty for cleanest results
- Split by newline to convert line-separated to numbered list
- Use space delimiter with trim to extract words from sentences
- Combine with other tools for advanced text processing
- Test with a small sample before processing large datasets
- Check the item count to verify expected number of splits
- Use for quick data format conversion without coding
Special Cases
Handling Special Characters
- Tab: Copy and paste an actual tab character
- Newline: Text is already split by lines by default
- Quotes: Use as delimiter if needed (", ')
- Backslash: Can be used as delimiter (\)
Edge Cases
- No Delimiter Found: Returns original text as single item
- Empty Input: Returns no items
- Consecutive Delimiters: Creates empty items (unless removed)
- Trailing Delimiter: May create empty last item
