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.

Hi Chandoo
As one of your students I have followed your detailed example through with great success. However, Excel is acting in an unexpected way and I wonder if you could take a look?
http://cid-95d070c79aef808e.office.live.com/self.aspx/.Public/Gantt%20Box%20Chart.xlsm
On my version, I have to type 40239 (Which equates to 2 Mar 2010) to get the chart to display 31 May 2010 (which should be 40329)!!??
Have I done something wrong or is Excel acting up?
Thx
Oli
PS Your example file in 2007 displays correctly.
Hi,
I like this idea a lot, but I agree the name is a little drab.
As an American I may just be seeing things, but to me the combination of lines and bars on your chart looks like a bunch of cricket bats.
Maybe you could work that into a catchier name. 🙂
Cheers!
Here is some code I use to keep the axis synched.
It may be useful to some of your readers
It is based on a comment I saw on Daily Dose of Excel.
Function SynchGanttAxis(Cname, lower, upper)
'Sets the X min and X max for Category axis
Application.Volatile
On Error Resume Next
'
'Top Horizontal Axis
With ActiveSheet.Shapes(Cname).Chart.Axes(xlCategory, 1)
.MinimumScale = lower
.MaximumScale = upper
End With
'Bottom Horizontal Axis
With ActiveSheet.Shapes(Cname).Chart.Axes(xlValue, 2)
.MinimumScale = lower
.MaximumScale = upper
End With
End Function
Function SynchVerticalAxis(Cname, lower, upper)
Application.Volatile
On Error Resume Next
' Excel 2007 only
'Right hand vertical axis
With ActiveSheet.Shapes(Cname).Chart.Axes(xlValue, 1)
.MinimumScale = 0
.MaximumScale = upper
End With
End Function
@Oli.. Can you check your file again.. I see 40329...
@Dave: Even I saw things.. the bars actually looked like lollipops. How about calling this lollipop chart - now that would be yummy and goes along the tradition of naming charts after eatables (bar, pie, donut...)
@Bob: Superb stuff... thanks for sharing 🙂
Hi Chandoo
This looks really good and I think it can also be applied to show project phases / milestones.
Question: Thinking further could this be amended to display a project lifecycle (Idea through to Implementation say 7 phases) on one bar / row? Just imagine 20 projects within a programme all on one chart one bar each showing their respective lifecycle stages i.e. on one page.
Idea: As the Gantt Box Chart this is quite intensive to set up re formatting etc how about the added extra of once you have completed this to "Save as template" i.e. saves the formatting and layout of the chart as a template so you can apply to future charts. Simple to do and will save the time formatting etc again and again and again.
Therefore tip: Click on your chart demo and then click on Save As template icon (2007) - edit file name and click on save. Ready to use / apply via Templates in Change Chart Type window.
Thanks and be very interested if the lifecycle question can be resolved
Mike
How embarrassing.
I was obviously suffering from numerical dyslexia. I was one of those days.
@Mike H: You can easily make this chart to work like a generic project lifecycle plan chart. All you have to do is,
1. in a separate sheet define the steps of lifecycle and various dates in a table (with 5 columns for each of the projects you have).
2. now use a control cell to input the project name you want to show in the chart
3. based on the input, use OFFSET Formulas to get the correct data
4. Rest is same as the tutorial above

Your solution is really smart but in the en Excel isn't meant to do stuff like this. I, as a former PM, always thought is was frustrating that you had to do stuff like this for something simple like a Gantt chart. So I built Tom's Planner. And would like to plug it here. I think it really solves the problem you are trying to solve in the most efficient way. Check out http://www.tomsplanner.com for a free account or play around with the demo.
Hi there,
Chandoo - this is really a very nice and helpfull chart - I adopted it, so I can report a forecast or the delay of a certain task (coming from my role as an auditor for projects).
One topic I´m currently struggeling with: I do have a project lasting for lets say 12 month. For a management reporting, I want to have kind of snapshot, lets say one month back and 2 month in the future. I tried with the offset formula, but failed. Any idea?
Thx
Lopi

Hi Chandoo - fantastic xls. One thing I can't figure out how to do is adjust the alignment of the vertical axis. I would like to left align so that I could indent to represent sub tasks. Can that be done? Or is there a better way?
I've been trying to work out if there's a way to show weekends on the graph. The closest thing I've got is to add them on a secondary axis, but then I haven't been able to keep both axis lined up together! Any ideas?
Following on from this - is it possible to show things like holidays?
