Remove duplicate rows without any Excel formulas.
You have a list with repeated entries — same customer appearing twice, duplicate
orders, names that got added more than once — and you want one clean copy of each. You
shouldn't have to learn COUNTIF or UNIQUE() to do that. Upload
the file, tell us which column to check for repeats, and download a deduplicated version
with a plain count of how many rows were removed.
How to do it
Upload the file, tell us which column to check for repeats (an email column, a SKU column, or the whole row), and download a deduplicated version. You get a plain-English summary first: how many rows were in your original file, how many were removed as duplicates, and how many unique rows remain — no formulas to copy, no helper columns to delete afterward. The tool shows you what it's going to remove before it removes it, and your original file is never touched.
Why "no formulas" matters
Excel's built-in Remove Duplicates button is on the Data tab, and most people don't find it on their first try. When they do find it and click it, there's no preview — it just deletes rows immediately, and if you had the wrong column selected, you might lose data you didn't mean to touch. The only recovery is Ctrl+Z, which only works if you haven't saved.
Check one column or the whole row
Most real-world duplicate problems are "same email address appearing twice" or "same SKU on two rows," not "every single cell in the row is identical." You can tell us to check a specific column — like the email column or the customer ID column — and keep only the first row with each unique value in that column. The other data on the row (name, date, amount) comes along with it.
If you want to match on every column — so a row only gets removed if it's completely identical to another row — that's an option too.
The extra-spaces problem (and why Excel sometimes misses duplicates)
A common reason "Excel says no duplicates but I can see them" is trailing spaces.
"john smith " with a space at the end looks the same as
"john smith" to human eyes, but Excel treats them as different values and
doesn't remove either. This tool trims whitespace before comparing, so those invisible
differences don't cause duplicates to slip through.
Need to find duplicates across two separate files — like matching your master list against a new import to see what overlaps? Compare two spreadsheets handles the cross-file case.
