## Analyze word frequency in a cell range

This article demonstrates two ways to calculate the number of times each word appears in a given range of cells. Excel 365 has many new functions that are really useful, I am using the REDUCE function combined with the LAMBDA and VSTACK functions here.

You can also use the TEXTJOIN and the TEXTSPLIT functions, however, they have a limit of 32 767 characters which the REDUCE function doesn't have.

This article also shows a user defined function (UDF) that will work for most Excel versions.

## 1. How to calculate word frequency in a given cell range - Excel 365 LAMBDA function

Excel 365 formula in cell E3:

Formula in cell F3:

The formula in cell F3 is explained here: Count how many times a string exists in a cell range (case insensitive)

### Explaining the formula in cell E3

#### Step 1 - Split string based on a space character

The TEXTSPLIT function splits a string into an array based on delimiting values.

Function syntax: TEXTSPLIT(Input_Text, col_delimiter, [row_delimiter], [Ignore_Empty])

TEXTSPLIT(x, " ")

#### Step 2 - Stack arrays vertically

The VSTACK function combines cell ranges or arrays. Joins data to the first blank cell at the bottom of a cell range or array (vertical stacking)

Function syntax: VSTACK(array1,[array2],...)

VSTACK(TEXTSPLIT(x, " "),TEXTSPLIT(y, " "))

#### Step 3 - Build the LAMBDA function

The LAMBDA function build custom functions without VBA, macros or javascript.

Function syntax: LAMBDA([parameter1, parameter2, â€¦,] calculation)

LAMBDA(x,y,VSTACK(TEXTSPLIT(x, " "),TEXTSPLIT(y, " ")))

#### Step 4 - Iterate through each cell in cell range B3:C12

The REDUCE function shrinks an array to an accumulated value, a LAMBDA function is needed to properly accumulate each value in order to return a total.

Function syntax: REDUCE([initial_value], array, lambda(accumulator, value))

REDUCE(,B3:C12,LAMBDA(x,y,VSTACK(TEXTSPLIT(x, " "),TEXTSPLIT(y, " "))))

#### Step 5 - Replace errors with -

The IFERROR function if the value argument returns an error, the value_if_error argumentÂ is used.Â If theÂ valueÂ argument does NOT return an error, the IFERROR function returns the value argument.

Function syntax: IFERROR(value, value_if_error)

IFERROR(REDUCE(,B3:C12,LAMBDA(x,y,VSTACK(TEXTSPLIT(x, " "),TEXTSPLIT(y, " ")))),"-")

#### Step 6 - Rearrange array to a single column layout

The TOCOL function rearranges values in 2D cell ranges to a single column.

Function syntax: TOCOL(array, [ignore], [scan_by_col])

TOCOL(IFERROR(REDUCE(,B3:C12,LAMBDA(x,y,VSTACK(TEXTSPLIT(x, " "),TEXTSPLIT(y, " ")))),"-"))

#### Step 7 - Extract unique distinct values from the array

The UNIQUE function returns a unique or unique distinct list.

Function syntax: UNIQUE(array,[by_col],[exactly_once])

UNIQUE(TOCOL(IFERROR(REDUCE(,B3:C12,LAMBDA(x,y,VSTACK(TEXTSPLIT(x, " "),TEXTSPLIT(y, " ")))),"-")))

## 2. How to calculate word frequency in a given cell range - UDF

This user defined function creates a unique distinct list of words and how many times they occur in the selected range.

### User defined Function Syntax

FREQWORDS(*cell_range, position*)

### Arguments

cell_range |
Required. The range you want to use. |

position |
Required. Which column to return. The first column contains the values and the second column contains theirÂ corresponding frequency. |

While executing this function,I am facing #value error in the entire column. Please help.

Sam,

This udf is created in excel 2007, what excel version do you have?

Did you remember to enter the second argument?

=FreqWords(B2:C11,

1)Did you create an array formula?

Hello Oscar,

first of all MERRY CHRISTMAS AND HAPPY NEW YEAR 2012- also Thank you very much for Word Frequency function.

I would like to ask if it is possible to convert it to a VBA Macro subroutine . I mean is it possible to use Freqwords function with in a sub(). I am novice to programming . please help.

Thank you very much sir.

Srinivas

Hi Oscar

Happy New Year 2012. Thank you very much for Word Frequency UDF. Forget about above request for sub(). I have found alternative.

Thank you

Srinivas

[...] Does this help?.... Excel udf: Word frequency | Get Digital Help - Microsoft Excel resource Example results from the above solution...... [...]

Hi Oscar,

I need your help to find the macro

I have many excel files with multiple sheets and each excel sheet

has many formula which are starting from perticular word e.g. FDS, FDSB, etc some formula has FDS, FDSB occur in the middle of the formula.

i need to find out how many times FDS,FDSB has been appear in the sheet(total count)

below is the formulae for your referance

=FISERROR(FDSB($D21, "IC_ESTIMATE_DATE(ALL, EXP_RPT, QTR, 3, 0, , , 'MM/DD/YYYY')@RC_ESTIMATE_DATE(ALL, EXP_RPT, QTR, +3, 0 , , , 'MM/DD/YYYY')"),"na)

in such a way there are many formulas in all the cells

i just need to count the how many times FDSB occur in one perticular sheet

please help

Rahul Jadhav,

Have you read this post:

Count multiple text strings in a cell range

Thank you

Rahul Jadhav,

Read this post:

Count text strings in formulas (vba)

Hi Oscar

Thanks for the reply this is what i was looking for thanks once again now i will apply it in all the worksheets.

One more thing i would like to ask is that

How can we identify any protected excel file before opening using macro VBA (e.g. i have a folder with multiple excel files i need to find out using macro how many files are password protected before opening and it should give result on separate workbook.)

is it possible using excel vba macro

Please reply

Best regards

Rahul Jadhav

Hi Oscar,

Thank you very much for the macro just to infrom you that it is working correctly

Thanks again

Hi Oscar,

Hope you are doing good!!!

My requirement is to copy data from ms excel and paste into ms word on specific position

>Both the files should get open automatically specially ms word

>macro should identify the user define cursor position in ms word file

>then paste the data where user wants to

>In this way i want to copy tables data, text, from excel into ms word on user define posion.

please check and let me know the suitable solution for the same

Have a nice time ahead

Thanking you in advance

Awesome function!!! Thanks so much for sharing this!

[…] Excel udf: Word frequency […]

hello oscar,

why u'r formula cannot use in new file?

thanks

boboy,

You need to copy and paste the VBA code to a module in your new file (workbook).

Thank you for that.

The only issue i'm facing is that only the first word of each cell is displaying after entering the formula. Not the full list of each single keyword.

For example, in your spreadsheet, the word "Air" appears 6 times in my list, and the frequency is correct (9).

What am I doing wrong?

Valentino,

you need to enter the formula as an array formula. There are instructions in this article on how to create an array formula.

How do you get the word frequency results in the array to sort by largest to smallest?

Hi great formula!

Quick question - my apologies in advance if it is dumb I typically do not work in Excel.

When I define the array for the results return I am assuming I know the number of unique words I have (in your example you knew there are 27 unique values?). But what happens if I don't know the number of unique words? I selected as an array the whole column but I get many #N/A and then it very inconvenient because I cannot delete these (it tells me I cannot change the array).

Is there a way for it automatically to decide the size of the array?

*I realize supposedly it is a small issue but I am working with a very large file more than 5000 companies that each have many tags and trying to sort the frequency of the tags and it gets messy.

Thanks in advance!

Julie

Is there a way for it automatically to decide the size of the array?Yes, Excel 365 subscribers don't need to enter this as an array formula. Excel takes care of the output and returns spilled values.

This UDF is for previous Excel versions. It will return blank values if the entered cell range is larger than the number of returned values.

Hi Oscar.

Much like Julie, I mod'ed the formula for a single column, removed the array because I am using Excel 365 and am getting the #NAME? error. I double checked the formula call to the function name and it reads the same. Not sue what else to do...

Michael

Hello again.

Nevermind... just found a thread that suggested adding in the module name infant of the function call, so I renamed the call to Module1.FreqWords and it worked.
