How To Iterate In Excel: A Step-by-Step Guide

Introduction

Learning to iterate in Excel is a fundamental skill for anyone looking to perform repetitive calculations or automate data tasks. Excel provides several methods to loop through data, such as using formulas, VBA scripts, or built-in features like the 'For Next' loop.

However, manual iteration in Excel can be complex, tedious, and time-consuming. We'll explore these methods and show how Sourcetable, an AI-powered spreadsheet platform, lets you skip the technical complexity by simply telling its chatbot what analysis you need - whether you're working with uploaded files or connected databases - and try it yourself at https://app.sourcetable.com/.

Iterating in Excel

Iterating with VBA Macros

Excel VBA macros enable advanced iteration through rows and columns for tasks like date comparison and data aggregation. Use the 'For', 'For Each', or 'Do While' loops in VBA to execute repetitive actions. 'For' loops require a counter, 'For Each' loops go through collections, and 'Do While' loops continue while conditions are true. The macro 'oneM_lag' exemplifies iteration by comparing dates, summing values, and lagging dates by one month.

Using Formulas for Iteration

Excel formulas offer iteration capabilities for managing spreadsheet data. The formula =IFERROR(IF($G14=L$4, IF($H1453,VLOOKUP($H14,Table2[#All],(COUNTIF($K14:K14, ">0")+2),), 0)*$E14, 0), 0) iterates to calculate weekly planned hours, set project durations, and eliminate errors. It employs a 'for' loop-like structure, a VLOOKUP function, and a COUNTIF function to count non-zero values.

Loop Types in Excel VBA

Excel VBA provides three loop structures for various iteration needs. 'For' loops with counters are ideal for a known number of iterations. 'For Each' loops are suited for object collections within Excel, such as ranges or sheets. 'Do While' and 'Do Until' loops are conditional, executing until the specified condition is no longer true, or becomes true, respectively. Use the 'exit' command within any loop to terminate it prematurely if necessary.
