Find Empty List Items

The Find Empty List Items tool helps you spot and extract blank lines in a list. Whether you’re managing user inputs, cleaning up copy/pasted text, or working with exported data, empty lines can sneak in and this tool helps you catch them fast.

Paste your list into the input box and the tool instantly shows all blank or whitespace-only entries. You can even show their line numbers, invert the results to show only non-empty entries, and choose whether to trim whitespace before checking.

No server upload, no fuss just quick, client-side results that work in any browser.

How to Use:

Start by pasting or importing your list into the left-hand box. As you do, the tool will scan each line and display only the empty ones (or non-empty, if you choose to invert the results) in the output box on the right.

Options:

• Trim Before Check: Removes spaces/tabs from each line before checking if it’s empty.
• Show Line Numbers: Instead of showing the blank content itself, you’ll see which line numbers are blank (e.g. “Line 3”).
• Show Non-Empty Instead: Flips the logic to return all lines that have content. Great for quickly cleaning out blank entries without deleting everything else.

Use the Copy button to grab the result, or Export to download it as a plain text file. The live count shows you how many lines matched.

What Find Empty List Items can do:

Sometimes blank lines are obvious. Other times, they’re sneaky like spaces, tabs, or invisible characters. Find Empty List Items helps catch those subtle gaps that clutter lists, confuse exports, or create unexpected formatting issues.

Let’s say you copy a list of email signups from a form:

[email protected]

[email protected]
     
[email protected]

With trimming on, this tool will detect three empty lines even though some contain invisible spaces. Turn off trimming, and it’ll only count truly blank lines ("") as empty.

If you’re editing CSVs, importing into databases, or creating mailing lists, having clean data matters. This tool lets you:

• Find and remove blank lines in data files
• Count and locate missing values in form exports
• Clean up lists copied from emails, PDFs, or documents
• Review messy bullet lists where some lines were accidentally skipped
• Prepare input for tools that reject or misread blank entries

Toggle on Show Line Numbers, and instead of seeing a bunch of empty lines, you’ll get something like:

Line 2
Line 4
Line 6

This makes debugging easier when you’re looking at logs, markdown files, code lists, or anything where structure matters.

You can also reverse the logic entirely and use the tool to extract only filled lines, helping you clean up or move data without editing it by hand.

It’s quick, lightweight, and runs entirely in your browser. No uploads. No tracking. Just clean, accurate results from any device.
