Split List Into Chunks

Split a list by items per batch, target batch count, or maximum characters and copy or download each generated chunk.

Guide

Split lists into practical API, campaign, and bulk-processing batches

Batch splitting can target a fixed number of items per chunk, a desired number of chunks, or a maximum character budget.

Each result remains independently copyable and downloadable. The source list is processed locally and is never submitted to ArrayText.

Common questions

Split List Into Chunks FAQ

How are target chunk counts calculated?

The tool chooses a ceiling chunk size so the output uses no more than the requested number of chunks.

What happens when one item exceeds the character limit?

That item remains in its own chunk because splitting inside a value would corrupt the list item.

Which chunk formats are available?

Text lines, JSON arrays, comma-separated values, and SQL value lists are supported.
