How to use Excel Text functions to separate first and last names in single columns

August 7, 2020
Paul Silverman

We were working with a client in Melbourne recently, and a question came up (yet again) about how to manage some text that had been imported into Excel from an external database. This is becoming more common, as the number of people increases who use Excel to manipulate data originating from outside databases. Why’s it necessary? It’s because database designers might be primarily concerned with capturing data, rather than thinking ahead to what the user will need to use the data for. Have a look at the example below, in column B: [caption id="attachment_3164" align="alignnone" width="300"]

The text (column B) as it came into our Excel sheet from an external database[/caption] As you can see, the data appears in Last Name, First Name format, with both names being separated by a comma. If we use this for a mail merge in Word, for example, it’s going to be difficult to customise our field so our mailout is addressed to either Dear John, or Dear Mr. Symons. Here’s how we can fix it. 1) Insert 6 blank columns. I’ve added headers to show you what’ll go where. You’ll remove 4 of these plus one other when were finished. It’ll look like the example below: [caption id="attachment_3165" align="alignnone" width="1024"]

Temporary working columns C through H added in[/caption] 2) In Column C we locate the position of the comma that separate the first and last name. The formula we’ll put in cell C2 is: =(FIND(",",B2,1)-1 This means: “find the position number of the comma in cell B2 starting at character position 1, then subtract 1 from that number to ignore the position number of the comma.” This is the result: [caption id="attachment_3166" align="alignnone" width="394"]

This is the result: [caption id="attachment_3167" align="alignnone" width="507"]

In Column E we use the following formula in cell E2: =LEN(B2) This means “what is the length of the character string in cell B2?” It looks like this: [caption id="attachment_3168" align="alignnone" width="634"]

It looks like this: [caption id="attachment_3169" align="alignnone" width="749"]

Isolating the first name[/caption] At this point we’ve isolated the first name and the second name. We’ll now copy the contents of copy Column F to Column G and Column D to Column H. We’ll use Paste Values here, because we don’t want to copy the formulas, just the resulting values. 6) Select the range F2:F7. Press Control-C to copy the content, click into cell G2, then press Control-V to paste. At first, G2:G7 will display #VALUE! error because it has copied the formula and this is generating an error, as shown below: [caption id="attachment_3181" align="alignnone" width="227"]

Using Paste Values to fix the error[/caption] The first names will now appear in column G. While they look the same as the contents of F2:F5, they’re different as F2:F5 contain formulas whereas G2:G5 contains only text. [caption id="attachment_3171" align="alignnone" width="269"]

Paste Values completed correctly[/caption] 8) Repeat this process, copying the list of last names from cells D2:D7 to H2:H7, remembering to Paste Values This is what you’ll have: [caption id="attachment_3173" align="alignnone" width="1024"]

Delete columns B through The result is this: [caption id="attachment_3174" align="alignnone" width="560"]
