It&#8217;ll count\nthe number o duplicates and sum them, so we will get a single result.<\/p>\n\n\n\n<p>Enter this formula, and press <strong>Ctrl + Shift + Enter<\/strong> to insert it as an <a href=\"https:\/\/support.office.com\/en-us\/article\/create-an-array-formula-e43e12e0-afc6-4a12-bc7f-48361075954d\">array formula<\/a>.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>=ROWS($A$2:$A$10)-SUM(IF(COUNTIF($A$2:$A$10,$A$2:$A$10)=1,1,0))<\/code><\/pre>\n\n\n\n<h2 class=\"wp-block-heading\">Count duplicate instances<\/h2>\n\n\n\n<p>Now, instead of counting all duplicates at once, let&#8217;s\nseparate them into different names, and count how many times the same name\nappears.<\/p>\n\n\n\n<p>Enter the following formula into cell <strong>D2<\/strong> and <a href=\"https:\/\/officetuts.net\/excel\/en\/training\/autofill\">AutoFill<\/a> them for other results.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>=COUNTIF($A$2:$A$10,C2)<\/code><\/pre>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"493\" height=\"287\" src=\"https:\/\/officetuts.net\/excel\/wp-content\/uploads\/sites\/2\/2019\/11\/count-occurences-of-duplicates.png\" alt=\"\" class=\"wp-image-4839\" srcset=\"https:\/\/officetuts.net\/excel\/wp-content\/uploads\/sites\/2\/2019\/11\/count-occurences-of-duplicates.png 493w, https:\/\/officetuts.net\/excel\/wp-content\/uploads\/sites\/2\/2019\/11\/count-occurences-of-duplicates-300x175.png 300w\" sizes=\"(max-width: 493px) 100vw, 493px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Count duplicate instances without the first occurrence<\/h2>\n\n\n\n<p>It&#8217;s very similar to the last method.
