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.

fields-for-mailmerge

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:

mail-merge-template-blank

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: 

  1. Place them in the same folder.
  2. Open the Word document.
  3. At this point, you should get an error. Click ok.
  4. This will open Data link properties dialog.
  5. Type the full path of the downloaded Excel workbook in the Data source field. Click ok (see image).
  6. 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.

    Some great contributions here.
    Gotta love the Friday 13th formula 😀

  2. Aires says:

    Great tips from you all! Thanks a lot for sharing! bsamson, particularly you helped me on a terribly annoying task. 🙂

    (BTW, Chandoo, it's not exactly "Find if a range is normally distributed" what my suggestion does. It checks if two proportions are statistically different. I probably gave you a bad explanation on twitter, but it'd be probably better if you fix it here... 🙂 )

    Great compilation Chandoo

    For the "Clean your text before you lookup"
    =VLOOKUP(CLEAN(TRIM(E20)),F5:G18,2,0)

    I would like to share a method to convert a number-stored-as-text before you lookup:

    =VLOOKUP(E20+0,F5:G18,2,0)

  4. Chandoo says:

    @Peder, yeah, I loved that formula
    @Aires: Sorry, I misunderstood your formula. Corrected the heading now.
    @John.. that is a cool tip.

    Hey Chandoo,

    That p-value formula is really great for a statistics person like me.

    What a p-value essentially is, is the probability that the results obtained from a statistical test aren't valid. So for example, if my p value is .05, there's a 5% probability that my results are wrong.

    You can play with this if you install the Data Analysis Toolpak (which will perform some statistical tests for you AND provide the P Value.)

    Let's say for example I've got two weeks of data (separated into columns) with the number of hours worked per day. I want to find out if the total number of hours I worked in week two were really all the different than week one.

    Week1 Week2
    10 11
    12 9
    9 10
    7 8
    5 8

    Go to Data > Data Analysis > T-Test Assuming Unequal Variances > OK

    In the Variable 1 Box, select the range of data for week 1.
    In the Variable 2 Box, select the range of data for week 2.
    Check "Labels"
    In the Alpha box, select a value (in percentage terms) for how tolerant you are of error.

    .05 is the general standard; that is to say I am willing to accept a 95% level of confidence that my result is accuarate.

    Select a range output.

    Excel calculates a number of results: Average (mean) for each week's data, etc.

    You'll notice however that there are two P Values; one-tail and two-tail. (one tail tests are for > or .05), the number of hours I worked in week two is statistically equivalent to the number of hours I worked in week one.

    So here’s a way you might want to use this. You put up a new entry on your blog. You think it’s the best entry ever! So you pull your webstats for this week and compare it to last week. You gather data for each week on the length of time a visitor spends on your website. The question you’re trying to prove statistically is whether there’s an average increase in the amount of time spent on your website this week as compared to last week (as a result of your fancy new blog post). You can run the same statistical test I illustrated above to find out. Incidentally, it matters very little to the stat test whether the quantity of visitors differs or not.

    Anyhow, the Data Analysis toolpack doesn't perform a lot of stat tests that folks like me would like to have access to. In those cases I have to either use different software, or write some very complicated mathematical formulas. Having this p-value formula makes my life a LOT easier!

    Thanks!

    Eric~

    Take FirstName, MI, LastName in access (you can fix it to work in excel) capitalize first letter of each and lowercase the rest and add ". " if MI exists then same for last name:
    Full Name: Format(Left([FirstName],1),">") & Format(Right([FirstName]),Len([FirstName])-1),"") & ". ","") & Format(Left([LastName],1),">") & Format(Right([LastName],Len([LastName])-1),"<")

    I teach excel, access, etc etc for a living and i have my access students build this formula one step at a time from the inside out to show how formulas can be made even if it looks complicated. Yes I know I could just do IsNull([MI]) and reverse the order in the Iif() function but the point here is to nest as many functions as possible one by one (also I illustrate how it will fail without the Not() as it is)

  8. Johan says:

    Extract the month from a date
    The easiest formula for this is =MONTH(a1)
    It will return a 1 for January, 2 for February etc.

  9. anjali says:

    if in a column we write the value of total person for eg. 10 if we spent 1.33 paise each person then how we get total amount in next column and the result will in round form plzzzzz solve my problem sir................... thank u

  10. Hui... says:

    @Anjali

    If the value 10 is in B2 and 1.33 paise is in C2 the formula in D2 could be =B2*C2

    If the values are a column of values you can copy the formula down by copy/paste or drag the small black handle at the bottom right corner of cell D2
