Advanced Text Splitter
Split text by delimiters, patterns, length, or custom rules with advanced filtering and formatting
The Advanced Text Splitter is a comprehensive tool for dividing text into parts using multiple methods and advanced filtering options. Whether you need to parse CSV data, split text into equal chunks, extract sentences, or use custom regex patterns, this tool provides professional-grade features for any text splitting task. Split by delimiters like commas or pipes, by character or word count, by sentences or paragraphs, into equal chunks, or using custom regex patterns.
Advanced filtering options let you remove empty parts, trim whitespace, eliminate duplicates, and filter by minimum or maximum length. Output formatting options include plain lists, numbered lists, JSON arrays, CSV format, and XML format. Add custom prefixes and suffixes, choose join separators, and export in multiple formats. The individual parts view lets you see each split section separately with its character count and copy individual parts with one click.
Perfect for developers parsing data files, writers organizing content, data analysts cleaning datasets, students processing research materials, or anyone working with structured text. Real-time statistics show the number of parts, total characters, average length, and shortest/longest parts. All processing happens instantly in your browser with complete privacy - your data never leaves your device. Export results as TXT, JSON, CSV, or XML files for use in other applications.
