How to use Find the Length of a List
- 1. Paste your list. Put your items into the input pane, one per line. It can be a to-do list, a pasted table column, or any block of text you want to treat as a list.
- 2. Decide how to treat blank lines. Turn on Ignore empty list items if stray blank lines shouldn't count toward the total. Leave it off if every line, blank or not, should be counted as an item.
- 3. Read the count. The output pane shows a single number: the total number of items in your list under the option you chose. Copy it wherever the count is needed.
When to use Find the Length of a List
Find the Length of a List counts how many items are in a pasted list. It is a quick way to answer 'how many rows are there' without opening a spreadsheet or writing a script.
- Confirming a CSV row count. You pasted a column from a CSV export and need to know how many entries it contains before setting up a batch job that expects a specific number of records.
- Checking an attendee list before an event. An RSVP list was pasted in from an email thread and you need the exact headcount for catering or seating, without manually counting each line by eye.
- Sizing a form's dropdown options. You are building a form with a dropdown and want to know exactly how many choices you have pasted in, so the select element and its validation logic match.
- Filtering out blank lines before counting. A pasted list has trailing blank lines from copying out of a spreadsheet. Turning on the ignore-empty option gives you the real item count instead of an inflated one.

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?
