How to quickly convert a whole column of numerics/non-numerics to text in Excel

What I love about my job is that, nearly every day, I have one of those "I didn't know that!" moments - for example, where I find out there is a quick way to do something that was otherwise quite tedious and potentially error prone.

I have regularly come across the problem in Excel where a column includes values that are generally numeric, but can also sometimes include an alphabetic character. Excel will often assume that the numeric value is number, when I really need the whole column to be treated as text. 

When this happens, it can cause problems for any formulae that try matching against the column values - if the formulae expects text, but the value stored is numeric. Changing the overall column format to text is not enough - the numeric values already in the column remain as numbers even when this is done.

In preparing one of the recent Boot Camp sessions for Microsoft Excel, I discovered that that there is such an easy way to convert a column like that so that all entries are text - with no need for formulae or copying and pasting values (which is what I used to do!)

Members of the iTandCoffee Club can access this week's handy hint, which looks at how to use an option in the Data tab of Excel to quickly and easily format an entire column as text.

Purchase 120 days' access to watch all 9 parts the Microsoft Excel Boot Camp series of videos. These 9 parts are being added each week over the period of 8/8/20 to 10/10/20 (excluding 28/8/20). (Note that the access period will become 90 days for purchases made after 10/10/20.)

Here's what's covered in each part:

Week 1 – Getting Started

In this first session of our Microsoft Excel Boot Camp, we start at the very beginning – creating a new Excel workbook and understanding Excel terminology – Workbook, Worksheet, Cell, Rows, Columns, Formulae. We take a guided tour of the main areas of the Excel app (the Ribbons); we look how to easily ‘zoom ‘your document to a size that suits your eyes; saving your document; re-opening your Excel file; and understanding where OneDrive fits in to the picture (and whether to save your Excel files there). We also look at the Templates that you can use to get started on your spreadsheet.

Week 2 – Creating a customer list with some simple formatting and formulae

In this second session, we use the example of a customer list, looking at: entering some simple data into your list; re-sizing columns and rows (manually and using ‘autofit’); text wrapping, entering different types of data into cells (eg text, integers, numbers, dates, dollars); how to select one or more cells (or whole rows / columns); formatting cells (size, bold, colour, background colour, number format, date format); selecting rows, columns and cells; inserting and deleting columns and rows. We then look at some basic formulae for adding the content of rows and columns, and how to copy formulae and formatting across the multiple cells.

Week 3 – Creating a standard invoice with calculations for GST and totals 

In Part 3, we look at the example of a standard invoice: how to format this invoice as an A4 sized page to include a business logo and business details; how to set up your invoice for entry of the items you wish to charge for; setting rows and columns to automatically calculate GST and totals; hiding the grid lines in printed version; including borders around required areas; turning the invoice into a Template that you can use over and over and how to access that template when you need it; setting up your worksheet so that it fits to a single page width; converting that invoice into a PDF that you can send via email and/or save somewhere on your computer/device.

Week 4 – Sorting, filtering, totals/sub-totals and finding/removing duplicates

Part 4 looks at working with data that needs sorting, sub-totalling, grouping or that has duplicates that need to be removed. We also look at the wonderful ‘filter’ options available, to allow you to more easily find the data you are looking for in what may be a very long list of rows – based on whatever criteria you specify.

Week 5 – Basic & Useful formulae PLUS data validation 

In part 5, we focus in this part on using Formulae in your workbook – looking at some of the more common formulae that relate to data in a single worksheet, and across multiple worksheets. We also look at how to set up data validations, which can help with data entry and consistency – setting up a ‘pick list’ of values and how this can ensure entered data is limited to this list.

Week 6 – Importing/exporting CSV files, working with sheets, conditional formatting

In Part 6, we look at importing a ‘comma-delimited’ file (a file in text format, with commas – or some other ‘delimiter’ separating the fields) into Excel format, and at how to create a CSV file from a sheet in your Excel workbook. We look at working with multiple sheets – adding, copying, renaming, moving, creating another workbook from a sheet, hiding, and protecting sheets. We also look at setting up conditional formatting that will automatically bold, colour, underline (or any other format) cells, columns and rows in your sheet.

Week 7 – Summarising and Reporting your data - Pivot Tables and Charts

Part 7 looks at how utilise the Pivot Table feature to see your data represented in a summarised format, counts, totals, averages and other functions reflected in this summarised format. We also look at presenting your data in charts that provide a wonderful visual representation of what is otherwise a flood of text and numbers!

Week 8 – All sorts of handy tips, shortcuts and formulae

In Part 8, we look at really handy shortcuts, features, formulae and tips – to help you use Excel efficiently and effectively. This session will capitalise and expand on what we have covered in earlier sessions, quick ways of achieving things that require several keystrokes and use of the mouse abd discovering great formulae that you may not realised are available.
