*The tutorial explains the Excel REPLACE and SUBSTITUTE functions with examples of uses. See how to use the REPLACE function with text strings, numbers and dates, and how to nest several REPLACE or SUBSTITUTE functions within one formula.*

Last week we discussed various ways of using FIND and SEARCH functions within your Excel worksheets. Today, we will be taking a deeper look at two other functions to replace text in a cell based on its location or substitute one text string with another based on content. As you may have guessed, I am talking about the Excel REPLACE and SUBSTITUTE functions.

The REPLACE function in Excel allows you to swap one or several characters in a text string with another character or a set of characters.

REPLACE(old_text, start_num, num_chars, new_text)

As you see, the Excel REPLACE function has 4 arguments, all of which are required.

**Old_text**- the original text (or a reference to a cell with the original text) in which you want to replace some characters.**Start_num**- the position of the first character within old_text that you want to replace.**Num_chars**- the number of characters you want to replace.**New_text**- the replacement text.

For example, to change the word "*sun*" to "*son*", you can use the following formula:

`=REPLACE("sun", 2, 1, "o")`

And if you put the original word in some cell, say A2, you can supply the corresponding cell reference in the old_text argument:

`=REPLACE(A2, 2, 1, "o")`

The REPLACE function in Excel is designed to work with text strings. Of course, you can use it to replace numeric characters that are part of a text string, for example:

`=REPLACE(A2, 7, 4, "2016")`

Notice that we enclose "2016" in double quotes as you usually do with text values.

In a similar manner, you can replace one or more digits within a number. For example:

`=REPLACE(A4, 4, 4,"6")`

And again, you have to enclose the replacement value in double quotes ("6").

As you have just seen, the REPLACE function works fine with numbers, except that it returns a text string :) Remembering that in the internal Excel system, dates are stored as numbers, you may try to use some Replace formulas on dates. Results would be quite embarrassing.

For instance, you have a date in A2, say 1-Oct-14, and you want to change "*Oct*" to "*Nov*". So, you write the formula REPLACE(A2, 4, 3, "Nov") that tells Excel to replace 3 chars in cells A2 beginning with the 4^{th} char… and got the following result:

Why's that? Because "01-Oct-14" is only a visual representation of the underlying serial number (41913) that represents the date. So, our Replace formula changes the last 3 digits in the above serial number to "*Nov*" and returns the text string "419Nov".

To get the Excel REPLACE function to correctly work with dates, you can convert dates to text strings first by using the TEXT function or any other technique demonstrated in How to convert date to text in Excel. Alternatively, you can embed the TEXT function directly in the old_text argument of the REPLACE function:

`=REPLACE(TEXT(A2, "dd-mmm-yy"), 4, 3, "Nov")`

Please remember that the result of the above formula is a **text string**, and therefore this solution works only if you are not planning to use the modified dates in further calculations. If you do need dates rather than text strings, use the DATEVALUE function to turn the values returned by the Excel REPLACE function back to dates:

`=DATEVALUE(REPLACE(TEXT(A2, "dd-mmm-yy"), 4, 3, "Nov"))`

Quite often, you may need to do more than one replacement in the same cell. Of course, you could do one replacement, output an intermediate result into an additional column, and then use the REPLACE function again. However, a better and more professional way is to use **nested REPLACE functions** that let you perform several replacements with a single formula. In this context, "nesting" means placing one function within another.

Consider the following example. Supposing you have a list of telephone numbers in column A formatted as "123456789" and you want to make them look more like phone numbers by adding hyphens. In other words, your goal is to turn "123456789" into "123-456-789".

Inserting the first hyphen is easy. You write a usual Excel Replace formula that replaces **zero characters** with a hyphen, i.e. adds a hyphen in the 4^{th} position in a cell:

`=REPLACE(A2,4,0,"-")`

The result of the above Replace formula is as follows:

Okay, and now we need to insert one more hyphen in the 8^{th} position. To do this, you place the above formula within another Excel REPLACE function. More precisely, you embed it in the **old_text** argument of the other function, so that the second REPLACE function will handle the value returned by the first REPLACE, and not the value in cell A2:

`=REPLACE(REPLACE(A2,4,0,"-"),8,0,"-")`

As the result, you get the phone numbers in the desired formatting:

In a similar manner, you can use nested REPLACE functions to make text strings look like dates by adding a forward slash (/) where appropriate:

`=(REPLACE(REPLACE(A2,3,0,"/"),6,0,"/"))`

Moreover, you can convert text strings into real dates by wrapping the above REPLACE formula with the DATEVALUE function:

`=DATEVALUE(REPLACE(REPLACE(A2,3,0,"/"),6,0,"/"))`

And naturally, you are not limited in the number of functions you can nest within one formula (the modern versions of Excel 2010, 2013 and 2016 allow up to 8192 characters and up to 64 nested functions in a formula).

For example, you can use 3 nested REPLACE functions to have a number in A2 appear like date and time:

`=REPLACE(REPLACE(REPLACE(REPLACE(A2,3,0,"/") ,6,0,"/"), 9,0, " "), 12,0, ":")`

So far, in all the examples we have been dealing with values of a similar nature and have made replacements in the same position in each cell. But real-life tasks are often more complicated than that. In your worksheets, the characters to be replaced may not necessarily appear in the same place in each cell, and therefore you will have to **find the position of the first character** that should be replaced. The following example will demonstrate what I'm talking about.

Supposing you have a list of email addressing in column A. And the name of one company has changed from "ABC" to, say, "BCA". So, you have to update all of the clients' email addressing accordingly.

But the problem is that the client names are of different length, and that is why you cannot specify exactly where the company name begins. In other words, you do not know what value to supply in the start_num argument of the Excel REPLACE function. To find it out, use the Excel FIND function to determine the position of the first char in the string "@abc":

`=FIND("@abc",A2)`

And then, supply the above FIND function in the start_num argument of your REPLACE formula:

`=REPLACE(A2, FIND("@abc",A2), 4, "@bca")`

As you see in the following screenshot, the formula has no problem with finding and replacing the old text with the new one. However, if the text string to be replaced is not found, the formula returns the #VALUE! error:

And we want the formula to return the original email address instead of the error. So, let's enclose our FIND & REPLACE formula in the IFERROR function:

`=IFERROR(REPLACE(A2, FIND("@abc",A2), 4, "@bca"),A2)`

And this improved formula works perfectly, doesn't it?

The SUBSTITUTE function in Excel replaces one or more instances of a given character or text string with a specified character(s).

The syntax of the Excel SUBSTITUTE function is as follows:

SUBSTITUTE(text, old_text, new_text, [instance_num])

The first three arguments are required and the last one is optional.

**Text**- the original text in which you want to substitute characters. Can be supplied as a test string, cell reference, or a result of another formula.**Old_text**- the character(s) you want to replace.**New_text**- the new character(s) to replace old_text with.**Instance_num**- the occurrence of old_text you want to replace. If omitted, every occurrence of the old text will be changed to the new text.

For example, all of the below formulas substitute "1" with "2" in cell A2, but return different results depending on which number you supply in the last argument:

`=SUBSTITUTE(A2, "1", "2", 1)`

- Substitutes the first occurrence of "1" with "2".

`=SUBSTITUTE(A2, "1", "2", 2)`

- Substitutes the second occurrence of "1" with "2".

`=SUBSTITUTE(A2, "1", "2")`

- Substitutes all occurrences of "1" with "2".

As is the case with the Excel REPLACE function, you can nest several SUBSTITUTE functions within a single formula to do several substitutions at a time, i.e. substitute multiple characters with a single formula.

Supposing you have a text string like "*PR1, ML1, T1*" in cell A2, where "PR" stands for "Project, "ML" stands for "Milestone" and "T" means "Task". What you want is to replace the three codes with full names. To achieve this, you can write 3 different SUBSTITUTE formulas:

`=SUBSTITUTE(A2,"PR", "Project ")`

`=SUBSTITUTE(A2, "ML", "Milestone ")`

`=SUBSTITUTE(A2, "T", "Task ")`

And then nest them into each other:

`=SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(A2,"PR","Project "),"ML","Milestone "),"T","Task ")`

Notice that we've added a space at the end of each new_text argument for better readability.

The Excel REPLACE and SUBSTITUTE functions are very similar to each other in that both are designed to swap text strings. The differences between the two functions are as follows:

- SUBSTITUTE replaces one or more
**instances**of a given character or a text string. So, if you know the text to be replaced, use the Excel SUBSTITUTE function. - REPLACE changes characters in a specified
**position**of a text string. So, if you know the position of the character(s) to be replaced, use the Excel REPLACE function. - The SUBSTITUTE function in Excel allows adding an optional parameter (instance_num) that specifies which
**occurrence**of old_text should be changed to new_text.

This is how you use the SUBSTITUTE and REPLACE functions in Excel. Hopefully, these examples will prove useful in solving your tasks.

What formula do I use to change 13-05-2019 08:51:51 format into 13/5/2019 08:51:51 format?

Thanks

When I import names from a SharePoint list I get the name, a semicolon, and then a number (example: Smith, John;#1234;#Jones,Mary:#567). This number is probably assigned by SharePoint when you add someone so they range from single digits to 5 digits for our company. I am trying to eliminate the "#" and the numbers. I can replace the "#" with a space using the substitute function but am having problems replacing the numbers due to the fact they are not a fixed number of digits. Also some cells could be a single name while others could have five or six names. Any insights?

Thanks a lot.....

I've found my solution.. It really helps me much

Excellent article explaining the REPLACE & SUBSTITUTE functions, and I was able to correct some phone numbers using the REPLACE example in the article. But what I need to do now, is replace the individual cells with the corrected formatting (i.e. phone number without formatting to phone number with appropriate formatting). The column that has the original values has some cells with correct data and other cells with the incorrectly formatted phone numbers. Is there a simple way (using a formula?) to replace the new formatted number (in column C) with the incorrectly formatted number (in column B). Not every number in the column is incorrect, only about 100 of a total of about 700 entries. I hope I was clear.

...i am trying to do a reverse score formula for a data...how do i replace numbers without having the formula repeat back on itself? so for example, if a participant answers a "1" to a question, i want the answer in the cell to come up as "5"...i want the numbers reversed for 1 through 5 (i.e. i want 1=5, 2=4, 3=3, 4=2, 5=1).

my formula was this:

=substitute(substitute(substitute(substitute(substitute(B5,"1","5"),"2","4"),"3","3"),"4","2"),"5","1")

what i ended up creating was a loop, i assume...because each "1" ended up being a "1" (because it made the initial change to "5", and then further along the formula changed that "5" into a "1"), and each "2" became a "2" (for the same reason). 3 4 and 5 were correct (because those numbers didnt show up again in the first position of the number string inthe formula).

So, how do i write the formula so i dont have a loop for those first two numbers?

thanks!
