Looping is an operation of repeating the same block of code multiple times. Excel offers a few types of loops, each best in different types of situations.<\/p>\n\n\n\n<h2 class=\"format wp-block-heading\">For Next Loop<\/h2>\n\n\n\n<p>This is the most common type of loop. In the&nbsp;<strong>FOR<\/strong>&nbsp;loop, you specify the value where the loop starts and where it finishes. The code between the&nbsp;<strong>FOR<\/strong>&nbsp;and&nbsp;<strong>NEXT<\/strong>&nbsp;statement gets repeated. Look at the following example.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">For value = 0 To 5\n    MsgBox (value)\nNext value<\/pre>\n\n\n\n<p>In the above example, the&nbsp;<em>MsgBox<\/em>&nbsp;will display the message 6 times, displaying numbers 0, 1, 2, 3, 4, and 5.<\/p>\n\n\n\n<p>Additionally, you can skip some values by using the&nbsp;<strong>Step<\/strong>&nbsp;value.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">For value = 0 To 5 Step 2\n    MsgBox (value)\nNext value<\/pre>\n\n\n\n<p>This time the&nbsp;<em>MsgBox<\/em>&nbsp;displays numbers: 0, 2, 4. Because the loop counts to 5 it won\u2019t get to number 6.<\/p>\n\n\n\n<p>In the following example, we have the array with the four names of the movies. This VBA code will display each name inside the&nbsp;<em>MsgBox<\/em>&nbsp;window.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">Dim movies(1 To 4) As String\n \nmovies(1) = \"Matrix\"\nmovies(2) = \"Lord of the Rings\"\nmovies(3) = \"Star Wars\"\nmovies(4) = \"The Shawshank Redemption\"\n \nFor Count = 1 To 4\n    MsgBox (movies(Count))\nNext Count<\/pre>\n\n\n\n<p>In the next lesson, I will present you with a similar example with the <strong>FOR..EACH..NEXT<\/strong>&nbsp;loop.<\/p>\n\n\n\n<h2 class=\"format wp-block-heading\">For Each Next Loop<\/h2>\n\n\n\n<p>In Excel VBA, you can use the&nbsp;<strong>FOR..EACH..NEXT<\/strong>&nbsp;loop. It loops through each object in a collection. It can be the collection of worksheets&nbsp;or a collection of elements in an array as presented in our example below.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">Dim movies(1 To 4) As String\nDim movie As Variant\n \nmovies(1) = \"Matrix\"\nmovies(2) = \"Lord of the Rings\"\nmovies(3) = \"Star Wars\"\nmovies(4) = \"The Shawshank Redemption\"\n \nFor Each movie In movies\n    MsgBox (movie)\nNext movie<\/pre>\n\n\n\n<h3 class=\"format caution wp-block-heading\">CAUTION<\/h3>\n\n\n\n<p class=\"caution\">You cannot declare the&nbsp;<strong>movie<\/strong>&nbsp;variable in the&nbsp;<strong>FOR..EACH..NEXT<\/strong>&nbsp;loop as&nbsp;<strong>String.<\/strong>&nbsp;It has to always be declared as&nbsp;a <strong>Variant.<\/strong><\/p>\n\n\n\n<h2 class=\"format wp-block-heading\">Do While Loop<\/h2>\n\n\n\n<p>Unlike the&nbsp;<strong>FOR&nbsp;<\/strong>loop, the&nbsp;<strong>DO..WHILE<\/strong>&nbsp;a loop doesn\u2019t have specified: start and end values, instead it loops as long as the condition is true.<\/p>\n\n\n\n<p>Look at the following example:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">Dim counter As Integer\ncounter = 0\n \nDo While counter &lt; 5\n    MsgBox (counter)\n    counter = counter + 1\nLoop<\/pre>\n\n\n\n<p>In this example, Excel checks the first value, which is 0. The condition is met, so the iteration of the loop is executed. The&nbsp;<em>MsgBox<\/em>&nbsp;window displays the value 0. The next values that also meet the condition are&nbsp;0, 1, 2, 3, and 4. When&nbsp;<em>counter = 5<\/em>&nbsp;then the condition is not met and the loop terminates.<\/p>\n\n\n\n<h2 class=\"format wp-block-heading\">Do Until Loop<\/h2>\n\n\n\n<p>The&nbsp;<strong>DO..UNTIL<\/strong>&nbsp;loop is very similar to the&nbsp;<strong>DO..WHILE<\/strong>&nbsp;loop. The difference between these two loops is that in the&nbsp;<strong>DO..WHILE<\/strong>&nbsp;loop the code is executed as long as the condition is&nbsp;<strong>True<\/strong>&nbsp;and in the&nbsp;<strong>DO..UNTIL<\/strong>&nbsp;loop it is executed as long as the condition is&nbsp;<strong>False.<\/strong><\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">Dim counter As Integer\ncounter = 0\n \nDo Until counter = 5\n    MsgBox (counter)\n    counter = counter + 1\nLoop<\/pre>\n\n\n\n<p>The&nbsp;<em>MsgBox<\/em>&nbsp;will display 0, 1, 2, 3, 4. When counter = 5 then the condition is met and the loop terminates.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>VBA, as well as other programming languages, offers loops.
