Concatenate Function Examples

Example 1 - Concatenating Simple Text

The Concatenate function is used in column C of the following example spreadsheet, to join together the text strings in columns A and B.

 Formulas:
 ABC
1ForenameSurnameCombined Details
2JaneSMITH=CONCATENATE( A2, " ", B2 )
3JohnDAY=CONCATENATE( A3, " ", B3 )
 Results:
 ABC
1ForenameSurnameCombined Details
2JaneSMITHJane SMITH
3JohnDAYJohn DAY

Note that, in the examples above, a space (encased in quotes) has been added to separate the forename and surname.


Example 2 - Concatenating Dates

The Concatenate function is used in cell D2 of the following example spreadsheet, to join together the text strings in cells A2 & B2 and the date in cell C2.

 Formulas:
 ABCD
1ForenameSurnameDOBCombined Details
2PaulJONES02/02/87=CONCATENATE( A2, " ", B2, ", DOB: ", TEXT( C2, "mm/dd/yy" ) )
 Results:
 ABCD
1ForenameSurnameDOBCombined Details
2PaulJONES02/02/87Paul JONES, DOB: 02/02/87

In order to concatenate the contents of cells A2, B2 and C2 of the above spreadsheet, with the date formatted correctly, we should use the Concatenate function as follows:

=CONCATENATE( A2, " ", B2, ", DOB: ", TEXT( C2, "mm/dd/yy" ) )

This formula returns the text string "Paul JONES, DOB: 02/02/87".

Note that, in the example above:

Concatenate Function Problem

Common Problem - Dates & Times

One of the most common Concatenate problems encountered by Excel users is that the function result shows a date or time as a number, as shown below:

 Formulas:
 AB
102/02/2016=CONCATENATE( "The Date is: ", A1 )
209:00 AM=CONCATENATE( "The Time is: ", A2 )
 Results:
 AB
102/02/2016The Date is: 40211
209:00 AMThe Time is: 0.375
Likely Reason

Dates and times in Excel are represented internally by numbers. It is simply the formatting of a cell that causes these numbers to be displayed as dates and times. Therefore, when an Excel date or time is supplied to the Concatenate function, the result displays the underlying numeric value.

Solution

This problem can be solved by using the Excel Text function to convert the date or time value into a text string. This is shown in the example spreadsheet below:

 Formulas:
 AB
102/02/2016=CONCATENATE( "The Date is: ", TEXT( A1, "mm/dd/yyyy" ) )
209:00 AM=CONCATENATE( "The Time is: ", TEXT( A2, "hh:mm am/pm" ) )
 Results:
 AB
102/02/2016The Date is: 02/02/2016
209:00 AMThe Time is: 09:00 AM

The date and time formatting types are explained further in the Excel Custom Number Format page.
