Counting the frequency of unique entries in an excel column

Question

I run a customer service department (I'm new to this so need to learn quickly) and I'm trying to get some analytics on our customer service requests. I have a table in excel documenting every individual service request and I would like a graph showing the total number of requests per customer.

I could write this manually (see below) but I would like it to automatically update as more service requests are entered.

I have tried looking for answers to this but can't find any that update automatically or that don't require a table elsewhere to be manually updated with each new customer. We often get new customers and I dont want to have to go back to this every time to update a reference table or customer list.

Surely there must be a way in excel to "Count all entries of each occurrence of a name in a column" in some kind of smart way?

I would really appreciate help with this! Thanks in advance!

Answer 1

Thank you everyone for your suggestions. I found a solution from multiple answers and comments.

I ended up going to my original table that I am using to create new service records. I added a column called "1" and just entered the number 1 in that column, for every row. I then "Hid" this column in the usual fashion.

I then created a pivot table from this table and selected to display columns "Customer" and "1" and used these columns to produce a bar graph. Here is the result (With the column "1" unhidden):

tl;dr: Excel is unable to do this in any smart way, create a column in the original table contianing the number 1 so when a pivot table is made, it will auto sum the 1's for entries from the same customer. Create a plot from this.

It disgusts me . . . but it works.

Answer 2

If you have 365 you could take advantage of spilled ranges.

• On your second image put =UNIQUE(Table1[Customer]) in cell B3.
• Put =COUNTIF(Table1[Customer],B3#) in cell C3 - this formula will spill to all your unique customers.

Create two names ranges:

• One called XAxis which references =Sheet1!$B$3#
• One called ChartValues which references =Sheet1!$C$3#

Create your chart:

• Set series value to =Sheet1!ChartValues
• Set axis to =Sheet1!XAxis

Change Sheet1 to whatever your sheet is called remembering to wrap with ' if it has a space in the name.

Answer 3

Better to use pivot tables.

If below is your data,

• Go to Insert > PivotTable

  • A popup will show like below

    

  • Specify the Table/Range

  • Specify also the Location (anywhere in the Existing Worksheet)

  • The view below will be displayed

    

• Click the Customer checkbox and also drag the Customer field to fill the VALUES box as shown in the image below

  

  • You desired table will be displayed as below
