Split Text Tool

Easy! Paste your list into the input box. Select 'Comma' as the Split By option. Then, in the 'Join With' section, select 'JSON Array'. The tool will instantly format your list as a valid JavaScript/JSON array like ["item1", "item2", "item3"]. You can copy or download the result immediately.

Regex (Regular Expression) allows you to split text based on complex patterns instead of simple characters. For example, using \\d+ will split the text every time it finds one or more numbers. Using [.,!?] splits at any punctuation mark. It's powerful for advanced text processing, data cleaning, and pattern-based extraction. If you're new to regex, start with simple patterns like \\s+ (whitespace) or use the preset options.

Yes! Simply check the 'Remove Duplicates' box in the options panel. The tool will filter out any repeated items from your list automatically, keeping only unique values. This works with any delimiter (commas, newlines, etc.) and is case-sensitive. Perfect for cleaning up contact lists, email addresses, or data exports.

The tool supports newlines (enter key), commas, semicolons, pipes (|), tabs, spaces, and custom characters you define. You can also use regex patterns for advanced splitting. Simply select from the dropdown or enter your own custom delimiter. Mix and match delimiters in regex mode for maximum flexibility.

Batch mode processes your text line-by-line instead of as one continuous block. Enable it to apply your splitting rules to each line independently. This is useful when you have multiple items (like a list of URLs or product names) and want to split each item's internal structure separately while keeping the list organized.

Yes, 100% safe. This tool runs entirely in your browser using client-side JavaScript. Nothing you type or paste is ever sent to our servers or stored anywhere. It works completely offline after the page loads, making it secure for sensitive data like customer lists, passwords, API keys, or confidential documents.

Yes! Click the 'Upload' button to load text files (.txt, .md, .csv, .log) directly. The tool can handle files of several megabytes in size. For extremely large files (100MB+), your browser's memory is the only limit. The tool processes everything client-side, so there are no server upload restrictions.

Use Regex mode and create a pattern like [,;|] to split by commas, semicolons, OR pipes. Or use [\\s,]+ to split by any whitespace or comma. Regex gives you complete control over complex splitting scenarios, like splitting by 'and', 'or', and '&' all at once: (and|or|&).

This is a delimiter-based splitter that breaks text at specific characters or patterns (commas, newlines, regex). An equal-parts splitter divides text into chunks of a fixed size (like every 100 characters). Use this tool when your data is already structured with separators. Use an equal-parts splitter for breaking long text into consistent reading blocks or character limits.

Absolutely! Use the 'Download' button to save results as a .txt file. You can also copy to clipboard with one click. The downloaded file will contain your split/joined text exactly as shown in the output area. For JSON arrays, the file will be properly formatted and ready to use in your code.
