Delete Empty List Items - Remove Empty Items from a List Online

What Is an Empty Item Remover?

The Delete Empty List Items tool lets you remove all empty and whitespace-only items from a list. You can split your list by a character or regular expression, remove blank entries, and join the remaining items with a custom separator.

How to Use the Delete Empty List Items Tool

Paste or type your list into the Input List text area.
Choose a Split Mode — use Split by a Symbol for a fixed character or Split by a Regexp for a pattern.
Enter the Input Separator that currently divides your items (e.g., \n for newlines).
Toggle Remove Invisible Items to also remove items that contain only whitespace characters.
Set a Join Symbol to connect the remaining items in the output.
The cleaned list appears instantly with statistics showing how many items were removed.

Common Use Cases

Clean up lists that have blank lines or empty entries from copy-pasting.
Remove whitespace-only items that appear as invisible garbage in data.
Prepare data for import into spreadsheets or databases by removing empty fields.
Normalize messy lists with inconsistent spacing and blank entries.

Frequently Asked Questions

What counts as an "empty" item?

An empty item is a string of zero length. When Remove Invisible Items is enabled, items that consist entirely of whitespace characters (spaces, tabs, newlines) are also considered empty and removed.

Can I split by a regular expression?

Yes. Switch to Split by a Regexp mode and enter a valid pattern. For example, [;,\s] will split on semicolons, commas, or any whitespace.

What does the "Remove Invisible Items" option do?

When enabled, items that contain only whitespace characters (spaces, tabs, newlines) are removed alongside completely empty items. This helps clean up lists with invisible garbage.

Can I keep the original format of my list?

Yes. Set the Join Symbol to the same separator used in your input to preserve the original format, or choose a new separator to reformat the cleaned list.

How do I know how many items were removed?

The tool displays the total item count, the number of items removed, and the count of remaining clean items above the output area.
