In Excel: use =COUNT(range) for numbers, =COUNTA(range) for any non-empty cell, or =COUNTIF(range, criteria) to count matches.
On this page7
Decide what you are counting: numbers (COUNT), all entries (COUNTA), or matches (COUNTIF).
In a blank cell type the function and select the range, e.g. =COUNTA(A1:A10).
For a condition, add it: =COUNTIF(range, ">100") or =COUNTIF(range, "Text").
Press Enter; copy across if you are counting several columns.
What this does
Counting splits into three jobs and three functions. COUNT tallies only cells containing numbers; COUNTA tallies every non-empty cell including text; COUNTBLANK tallies the empties. When you only want cells meeting a condition, COUNTIF (one rule) and COUNTIFS (several) do the filtering for you. Most people learn this as a sequence of clicks and forget it by next week; learning it as a pattern instead is what lets you apply it to the next, slightly different version of the problem without starting from scratch. That is the difference this page is trying to make. The difference between a quick fix and a sheet you can trust is the extra minute you spend validating “count errors in excel”. 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 calculation you can defend to a CFO or an auditor, but the practical win is that someone else can open the file and understand what happened without asking you.
A worked example
In a list A1:A10 with some blanks, =COUNTA(A1:A10) returns how many cells have anything in them, while =COUNT(A1:A10) returns only the numeric ones. To count orders over €100, =COUNTIF(A1:A10,">100"). To count "North" entries in column B, =COUNTIF(B1:B10,"North"). Counting answers the “how many” questions that drive every report — orders placed, tickets open, rows matching a filter. Picking the right one of COUNT, COUNTA and COUNTIF is the whole skill. 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 “count errors in excel”, 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
COUNTwhen you meanCOUNTA—COUNTskips text and returns too few. - Putting the criteria without quotes (">100" needs the quotes).
- Counting a range that includes the header row, inflating the total by one.
- Expecting
COUNTIFto be case-sensitive — it is not; use EXACT insideSUMPRODUCTfor case rules.
Frequently asked questions
COUNT vs COUNTA?
COUNT only counts numbers; COUNTA counts any non-empty cell, text included. For empties, use COUNTBLANK.
How do I count with two conditions?
Use COUNTIFS: =COUNTIFS(B1:B10,"North",A1:A10,">100") counts rows that are North AND over 100.
How do I count unique values?
In modern Excel and Google Sheets, =COUNTA(UNIQUE(range)) counts distinct entries in one step.
