The idea of mail merge is simple & powerful. Imagine you handle recruitment at a large company. You just hired 300 analysts for the big data division. The next job – generate employment offer letters for each of them. Of course, you don’t want to type these letters one at a time. You have the details of all the 300 offers (name, email, address, offer code, role, benefit package details and date of joining etc.) in a spreadsheet. You also have a template of the offer letter.
Enter mail merge. This powerful feature combines MS Word documents with (Excel) data to generate all the 300 letters in just few minutes.

You can use mail merge in many similar situations – like generating invoices, address labels, certificates etc.
Read the below tutorial to learn how to set up mail merge in Word.
Tutorial – using mail merge to generate invoices
For this tutorial, let’s pick the example of generating invoices.
Step 1 – Create a workbook with your data
Let’s say your invoice has 11 fields, as shown below.

Create a workbook with 11 columns and load data as shown below.

Step 2 – Create an invoice template in MS Word
Open a new document in MS Word and create a document structure that reflects your invoice. You may download the invoice template for inspiration.
At this stage, our invoice looks like this:

Step 3 – Activate Mail Merge

Go to Mailings ribbon in MS Word and click on “Start mail merge” button. Choose the document type that best describes what you are doing (for invoices, you can choose either letter or normal word document)

This activates mail merge mode on your document.
Step 4 – Load data

Now, we need to load the field data. Click on “Select recipients” and choose “Use an existing list”. This opens File>Open dialog. Navigate to the folder where you saved Excel workbook with invoice data and select the file.
Step 5 – Insert fields at right places
Now that we have a list of fields, load them at necessary location in the invoice template using the “Insert Merge Field” button.
Pro tip: You can use Rules option to set up If then rules based on field values. (for example, if the payment reference # is empty, you can show different text)
At this stage, our invoice looks like this:

Step 6 – Preview & complete mail merge

Using the preview results area, check if everything is ok. Once you are ready, click on “Finish & Merge” to generate individual word documents or emails or prints of the invoices.
Pro tip: If you have a PDF printer, you can use that to generate PDFs for each invoice automatically.
Download Mail Merge tutorial files
There are 2 files in this tutorial – Excel workbook with invoice data & Word document with mail merge setup.
After downloading the files:
- Place them in the same folder.
- Open the Word document.
- At this point, you should get an error. Click ok.
- This will open Data link properties dialog.
- Type the full path of the downloaded Excel workbook in the Data source field. Click ok (see image).
- This should establish the connection for you.
Do you mail merge?
Mail merge is a very powerful and time saving feature. I use it often when I need to generate a lot of documents in one go.
What about you? Do you use mail merge? Please share your experiences & tips in the comments section.















21 Responses to “Distinct count in Excel pivot tables”
The distinct count option works well but I have found that if I have a date field and want to group by year, month, etc. that option seems to be disabled. I need to do both, distinct count and group by year/month.
Example data; sales orders with item quantities with dates.
Challenge; sum the item quantities, count the distinct orders and group by month. How do I do this?
Perhaps that's not possible due to the grouping?
@Al... When you use data model based pivots, you cannot group values manually anymore. Why not use Excel 2016's default date grouping option? In this case we have just a few dates, so Excel is not grouping them, but if you have an year's worth of data, when you make the pivot with date in the row label area, Excel automatically groups them. If you have fewer dates or want to use your own grouping, just create a table with all dates, add columns with month, week, year etc. Then connect this table (these types of tables are usually called as calendar tables) to your data on date field as a relationship. Now you can create reports by month, quarter etc easily.
Is this the only way to do it in 2013? I find it rather cumbersome to have to create another data table listing dates with the another column for MONTH() and YEAR() to be able to summarise data for senior level...
I know people find adding calendar tables cumbersome, but it is a best practice and let's you add more layers of analysis quite easily. For example, adding analysis by weekday vs. weekend or by financial quarter or YTD calculations (you would need either Power Pivot DAX or some very carefully setup pivot table value field settings)
I had absolutely no idea this was possible. Very useful, nice work!
Doesn't work for 2010 version though (or at least not my works version)
Hi ,
The post has the following in it :
These instructions work only in Excel 2016, Office 365 and Excel 2013.
when i have 2 different Pivot tables, one without the enabled “Add this data to data model” option, and the other one with it enabled.. is there anyway i can link slicers between them?
if the answer is NO,, what to do ?
Quick note, the “Add this data to data model” option is not available for the Mac version.
perhaps outside scope of this article but I have found when I attempt to create a pivot table from an external data source (connection to a sql view) the "Add this data to data model" becomes greyed out. Anybody experienced and found a solution so I can start getting distinct count in my pivot tables?
Is there a way to still add a calculated field when using distinct count?
I found I can't change the date source after tick the " add this data to the data model", can you help to adv how to change the date source in such case?
Is there a way to update the source once you have added to the data model? I receive a new spreadsheet weekly and would like to update the connection so my tables pull from the new source.
Hi Crhis, I like how you have hulk (superhero) as your avatar. Do you know that there is a superhero in Excel too? It's Power Query. You can use it to solve your problem in a simple click. Here an intro if you need some guidance.
Powerful Introduction to Power Query
A big Thank you. It worked.
Hi, have survey data that I need to analyze but the challenge is that my key fields are showing horizontally. I tried to transpose the fields using Power Query, but unfortunately the new fields are returning same values on a pivot table despite using distinct values
How I can a do a pivot table with discount conts in some columns and then generate shor report filter pages. pls it drives crazy
Hi. Why grand total pivot of distinct count is 13? shouldn't it be 67?
Great Answer! Saved me lots of time!
Thank you!!!
Worked awesome! Thanks!!
Hi Chandoo,
I am using pivot tables for distinct count and now I need to update them with new set of data. But when I update the source data, all the columns and formatting of Pivot table disappears and I need to build it from Scratch.
Is there a possibility that I can update the source data with new rows added and also retain my pivot tables?
