How to use Extract a Sublist from a List
- 1. Paste your list. Enter your items into the input pane, one per line. Any list where you need a specific contiguous portion works here.
- 2. Set the start position. Enter the item number to begin extracting from in Start position, using 1-based counting so the first item in the list is position 1.
- 3. Set how many items to take. Enter the count in Number of items. That many consecutive items are pulled starting from your chosen position, in their original order.
- 4. Copy the extracted sublist. The output pane shows just the items in the requested range. Copy the sublist wherever that specific portion is needed.
When to use Extract a Sublist from a List
Extract a Sublist from a List pulls a specific run of consecutive items out of a longer list, based on a start position and a count. Use it whenever you know exactly where in the list the section you need begins.
- Getting a specific batch from a numbered list. A list of order numbers is processed in fixed-size batches, and extracting items starting at a known position with a set count gives you exactly the next batch to handle.
- Pulling a known range of rows for spot-checking. You know that rows twenty through twenty five of a data export are worth a closer look, and extracting that exact range shows just those items.
- Isolating a section of a step-by-step list. A long numbered procedure has a section you need to review or copy separately, and extracting the items starting at that step's position gives you just that section.
- Recreating a page of results from a stored list. A list represents all results from a search, and extracting a fixed number of items starting from a known offset reproduces one page of that result set.

About the Extract a Sublist from a List tool
Extract a Sublist from a List runs as plain JavaScript in your browser tab, with no server behind it. Extract based on start and stop indexes. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's List Tools section, 114 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with 2 settings, including Start position (1-based) and Number of items, and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Is Extract a Sublist from a List free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
