Using Loop in VBA in Microsoft ExcelIn this article, we have covered different kinds of loops used in VBA and how to use them to accomplish the same task in different ways.Why Loops?Looping is one of the most powerful programming techniques used across many programming languages. Looping is used to repeat a block of code for required number of times or until a given condition evaluates to true or a specific value is reached, after which the next block of code is executed.The purpose of an Excel VBA loop is to make Excel repeat a piece of code certain number of times. One can specify how many times a code must be repeated as a fixed number (e.g. Do this 10 times), or as a variable (e.g. Do this as many times as there are rows of data).Excel Loops can be constructed in different ways to suit different circumstances.
Often, same results can be obtained in different ways to suit your personal preferences.There are three different kinds of loops available in Excel VBA, which are:1. DO UNTIL Loop2.
The For Next and For Each Loops Explained for VBA & Excel. July 26, 2017. Jon Acampora. I have coding for consolidation, but i need to run the ” Do while loop ” coding for if sheet not available need to consolidate all those file in folder file availability. I am quite familiar with the For Next and For Each Next loops (as. The following code example uses the Continue While statement to skip to the next column of an array if a divisor is zero. The Continue While is inside a For loop. It transfers to the While col lastcol statement, which is the next iteration of the innermost While loop that contains the For loop. Jun 19, 2018 Continue For loop. Ask Question. Loop While False 'quit after one loop Next i share improve this answer. Answered Jan 19 '15 at 20:39. Arlen Beiler Arlen Beiler. 5,289 28 75 124. This looks to be the neatest way to get out of using Goto for continuing For loops I've seen. Next without For in nested loops excel VBA-3.
DO WHILE Loop3. DO UNTIL LoopThe DO UNTIL Loop is used to repeat a block of code indefinitely, until the specified condition is set to True. The condition can either be checked at the beginning or at the end of the Loop. The DO UNTIL LOOP statement tests the condition at the beginning, whereas the DO LOOP UNTIL statement tests the condition at the end of the Loop.Syntax of DO UNTIL LOOP statementDo Until ConditionBlock of code to be repeatedLoopSyntax of DO LOOP UNTIL statementDoBlock of code to be repeatedLoop Until ConditionWe have explained DO UNTIL loop with an example. Loop1 and Loop2 macros are used to calculate the average of numbers in column A and column B using the DO UNTIL loop.Sample data is present in the range A15:B27. Column A contains scores of Round 1 and column B contains scores of Round 2.
We want to calculate averages of scores in Round 1 and Round 2 in column C.In Loop1 macro, we have used “FormulaR1C1” to insert average formula in the active cell. Condition statement in the DO UNTIL loop is checked at the end of the loop.In Loop2 macro, we have used “WorksheetFunction.Average” to insert average value in the active cell. Even in this macro, condition statement is checked at the end of the loop.The only difference between Loop1 and Loop2 macro is that Loop1 inserts the average formula, whereas Loop2 calculates the average and then inserts the average value in the active cell.2. DO WHILE LoopThe DO WHILE Loop is used to repeat a block of code indefinite number of times, while the specified condition continues to be True and stops when the condition returns False. The condition can either be checked in the beginning or at the end of the Loop. The DO WHILE LOOP statement tests the condition in the beginning, whereas the DO LOOP WHILE statement tests the condition at the end of the loop.
The DO LOOP WHILE statement is used when we want the loop to run the block of code at least once before checking for the condition.Syntax of DO WHILE LOOP statementDo While ConditionBlock of code to be repeatedLoopSyntax of DO LOOP WHILE statementDoBlock of code to be repeatedLoop While ConditionIn this example, Loop3 and Loop4 macros are used to calculate averages for values in cells of column A and column B. Both macros work on the same sample data as used by macros Loop1 and Loop2. Both use DO WHILE statement to loop through the range which contains the data.The only difference between Loop3 and Loop4 macros is that they are different ways of representing conditions of DO WHILE loop.As Loop3 and Loop4 macros use same input data and even perform same functions as Loop1 macro, so that the output returned will also be same as of Loop1 macro.3. FOR loopThe For Loop is used to repeat a block of code for specific number of times.Syntax of FOR loopFor countvariable = startvalue To endvalueblock of codeNext countvariableLoop5 macro shows how to use FOR loop to calculate the average. It also uses the same sample data used by other macros.
Excel Vba Do While Loop Continue
We have used 15 as starting value as the sample data starts from the 15 th row. We have used Range(“A” & Cells.Rows.Count).End(xlUp).Row to find the last row containing data. FOR loop will repeat (lastcell- 15) number of times.Output returned after running Loop5 macro is same as of Loop1 macro.Loop6 macro is created to calculate average, only if the active cell which will have the average function is empty before running the macro.Sample data for this macro is present in the range E15 to G27.We have used DO LOOP WHILE to loop through the defined range. IF statement is used to check whether the cell where function will be inserted, contains a value. This macro will insert average function to the cell only if it is empty.Loop7 macro is also used to calculate average.
It checks for values in the helper column before evaluating whether to loop again. It also checks whether the cell reference to be used in the average function is empty.Sample data used for Loop7 macro is in the range J15:M27.Column M is used as helper column. This macro will insert an average function only if a cell in column M is non empty. This macro checks that a cell should be empty before inserting an average function in it. If I talk about exercise 5 the given code is not working properly.
After running the macros It is giving result for C1 only.A B C67The code is:Sub Loop3‘ This loop runs as long as there is something in the NEXT column‘ It does not calculate an average if there is already something in the cell‘ nor if there is no data to average (to avoid #DIV/0 errors).DoIf IsEmpty(ActiveCell) ThenIf IsEmpty(ActiveCell.Offset(0, -1)) And IsEmpty(ActiveCell.Offset(0, -2)) ThenActiveCell.Value = “”ElseActiveCell.FormulaR1C1 = “=Average(RC-1,RC-2)”End IfEnd IfActiveCell.Offset(1, 0).SelectLoop Until IsEmpty(ActiveCell.Offset(0, 1))End Sub. Pls ignore the last one:If I talk about exercise 5 the given code is not working properly. I am 80 years old male and trying to prevent debenture, hence taking up excel,but would be happy to get any information at all.I have started by working out my Gas bill.
The main problem i am having is try to transfer data from one point to another.I have set it out to produce cost Daily, Weekly and Yearly, i would like to transfer that data to a table sort of; using one row across four columns including the date, all from the calculations filling the columns row by row.Sorry i may seem simple compared to you Excel cleverer people, but I am just learning the basics.thanks a lot.
