What happens when you run this tool
Truncate a list to a specific number of items.
The main value here is precision. You can inspect the transformation before the content goes into code, documentation, a spreadsheet, or another parser.
How the transformation behaves
Truncate List applies a focused transformation to the input so you can compare the before and after without writing a custom script for a one-off task.
List tools usually treat each line or separator-delimited value as a discrete item, so separators and blanks affect the result.
This tool is deterministic: the same input and the same settings produce the same output every time. All processing happens in your browser, so your input stays on your device during the transformation.
Practical situations where it helps
Shorten long lists quickly.
Keep only the first or last items.
Prepare preview subsets.

Input expectations and common surprises
Unexpected output usually comes from one of three places: the wrong unit of transformation, hidden formatting in the source, or an option that changes the rule being applied.
For deterministic tools, the same input and the same settings should reproduce the same result. If not, the input likely changed in a small but meaningful way.
