Excel COUNT UNIQUE Text Values

What this does

Counting duplicates is really two questions. To see how often each value occurs, COUNTIF(A:A,A2) returns the frequency for that row — 1 means it is unique, anything higher means it repeats. To count how many distinct values a list contains, the classic =SUMPRODUCT(1/COUNTIF(range,range)) adds a fraction for each cell so every group of identical values sums to exactly 1; in Microsoft 365 the simpler =ROWS(UNIQUE(range)) does the same job. The same idea underpins a lot of everyday Excel work, so the few minutes spent getting it right here pay back across every sheet you build afterwards. Treat it as a pattern, not a one-off, and it stops being something you look up and starts being something you reach for. The difference between a quick fix and a sheet you can trust is the extra minute you spend validating “excel count unique text values”. Start on a copy or a tiny sample, keep the affected cells visible, and compare the result with the outcome you expected before you touch the real workbook. When a formula is involved, keep the inputs labelled beside it, reference cells instead of typing values, and apply number formatting only after the result checks out. The point is a data step that keeps your analysis trustworthy, but the practical win is that someone else can open the file and understand what happened without asking you.

A worked example

A column A2:A9 of fruit reads Apple, Pear, Apple, Plum, Apple, Pear, Kiwi, Plum. Put =COUNTIF(A:A,A2) beside it: Apple shows 3, Pear shows 2, Plum shows 2, Kiwi shows 1. To count the distinct fruits, =SUMPRODUCT(1/COUNTIF(A2:A9,A2:A9)) returns 4 (Apple, Pear, Plum, Kiwi), and =ROWS(UNIQUE(A2:A9)) returns the same 4 in 365. Counting duplicates answers the questions a flag cannot: how concentrated is the data, how many real customers are in a list of 5,000 rows, which value repeats most. It is the measurement step between spotting duplicates and deciding what to do about them. Check the referenced cells, argument order and result type in your workbook. Start with the worked example before changing an input, then compare the changed result with the calculation you expected. An error value or a result of a different type is a reason to inspect the inputs and arguments.

In Google Sheets

The standard worksheet functions used by this example are listed in Google Sheets. Check the cell references, argument separators and input types in the target spreadsheet, then compare the worked result. This formula-availability check does not establish identical menus, keyboard shortcuts or workbook features, and it is not a product execution test. Nothing on this page is behind a login or a download: the exact answer is at the top, and the detail below it is there for when you need it. That is the whole promise here — the answer first, and just enough context to make it stick. For “excel count unique text values”, keep the input cells and the result visible while you check the formula in Excel. Follow the worked example and change one input at a time. The steps explain the workbook calculation; this page does not run a live calculator for that task.

Common mistakes

• Using a whole column (A:A) inside SUMPRODUCT(1/COUNTIF(...)) — the empty cells divide by zero and throw #DIV/0!; pin it to the exact range.
• Confusing the two answers: COUNTIF gives a per-row frequency, not the number of distinct values.
• Forgetting that COUNTIF is case-insensitive, so "apple" and "Apple" count as the same value.
• Letting blank cells into the distinct-count range, which the 1/COUNTIF trick cannot divide.
