List Chunker
Split a list into fixed-size chunks — batch IDs or rows for APIs, one item per line — 100% in your browser, no upload
Enter a list above to split it into fixed-size chunks.

Split a list into fixed-size chunks
Paste a list with one item per line, set a chunk size, and each line is grouped into batches of that size — the last batch holds whatever is left over. Optionally trim each line and drop blank lines so stray whitespace and empty rows do not throw off the counts. Everything runs in your browser, so your list is never uploaded.
Why batch a list
Many APIs cap how many IDs, rows, or records you can send per request. Chunking a long list into fixed-size groups lets you page through it one request at a time, build bulk-insert statements, or paste manageable batches into a spreadsheet or form. Each chunk has its own copy button for exactly that.
Frequently asked questions
What happens to the last chunk if the list does not divide evenly?
The final chunk holds the remaining items. A list of 10 items split by 3 gives chunks of 3, 3, 3 and 1.
Does it trim whitespace or remove blank lines?
Both are optional toggles. Trim strips leading and trailing spaces from each item, and Drop blank lines removes empty rows (including a trailing newline) before chunking.
