Line Grouper (Group Lines by Count)
Split and chunk large lists of text or data into batches of N lines each. Organize entries into groups of 2, 3, 5, 10, or custom sizes separated by empty lines, horizontal rules, or custom delimiters. 100% private and client-side.
Step-by-Step Instructions
Paste Multi-Line Data
Input your list of items, log lines, CSV records, or text entries into the text area.

Export Structured Text
Copy the clustered, neatly partitioned text or download the organized dataset.

Frequently Asked Questions
How does chunk-based line grouping work?
Chunk grouping divides a list of N lines into distinct sub-batches of a fixed size (e.g., grouping 1,000 lines into chunks of 50 lines). Each chunk is separated by your chosen delimiter, making it easy to create batches for API rate limits or bulk email sending.
Can I group lines by common prefix or file extension?
Yes. You can group lines sharing common prefixes, domains, or file extensions (e.g. clustering URLs by domain or grouping file paths by directory structure).
How is this tool useful for database administrators and programmers?
It allows developers to split massive datasets into manageable batches (e.g., chunking 10,000 IDs into batches of 500 for SQL IN (...) queries or batch database INSERT statements).
Is my text data stored or sent to any remote server?
No. All text parsing, splitting, and regrouping logic executes locally in your browser session via client-side JavaScript.
