Using Excel As Your Database

This is a guest post by Vijay, our in-house VBA Expert.

Often I have thought, if I could have write “Select EmployeeName From Sheet Where EmployeeID=123” and use this on my excel sheet, my life would be simpler. So today we will learn how to do this.

People spend a lot of time thinking whether to use Excel as their database or not. Eventually they start using Access or SQL Server etc.

Today we will learn how to use Excel as a Database and how to use SQL statements to get what we want.

Excel as a Database – Demo

We will learn how to build this:

Using Excel as your Database - demo

Before we begin:

  1. The entire sheet (where the raw data has been stored) will be referred as one single database table by Excel. This is very important to understand.
  2. This has nothing related with the in-built Table (2007 and greater) / List (2003 and previous) feature of Excel.
  3. If you know SQL (Structured Query Language) your task becomes much easier.

Setting up Excel as Database

We need some raw data and we will utilize Customer Service Dashboard sample database here.

Let’s get started.

First we will design the structure of what all option we want to present for filtering the data, which you can see in the interface below.

Once the user clicks on Show Data we will use a SQL statement to filter-out the data as per the drop down options selected by the user and the put them in the table below.

We will also use another SQL statement to populate the top right hand side table for calls data when all the 3 drop downs have some options selected.

Screen Design

Adding Active-x data objects reference

We need to add a reference to the Microsoft ActiveX Data Objects Library to be able to use the worksheet as a database table. You can do this from Visual Basic Editor > Tools.

VBA References

I usually select the most recent version, however if you are developing a product it will be best suited if you are familiar with the operating system and office version used by the end-user’s system and accordingly select the best version available.

Opening Excel as a Database

Once this is done we need to hit the road with some VBA code.


Public Sub OpenDB()
If cnn.State = adStateOpen Then cnn.Close
cnn.ConnectionString = "Driver={Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb)};DBQ=" & _
ActiveWorkbook.Path & Application.PathSeparator & ActiveWorkbook.Name
cnn.Open
End Sub

The above procedure is the heart of this post, this is where we define how to use the current Excel workbook as our database.

cnn.ConnectionString = "Driver={Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb)};DBQ=" & _
ActiveWorkbook.Path & Application.PathSeparator & ActiveWorkbook.Name

On this line, we define all the possible file extensions that we are allowed to create an Excel Workbook and then use as our database.

Let’s understand the code module

When you click on the Update Drop Downs button, the VBA code uses the “Data” worksheet as a table and then finds unique values for Products, Region and Customer Types and then populates them as ListItems for the ComboBox controls.

Example for Products drop down


strSQL = "Select Distinct [Product] From [data$] Order by [Product]"
closeRS
OpenDB
cmbProducts.Clear
rs.Open strSQL, cnn, adOpenKeyset, adLockOptimistic
If rs.RecordCount > 0 Then
Do While Not rs.EOF
cmbProducts.AddItem rs.Fields(0)
rs.MoveNext
Loop
Else
MsgBox "I was not able to find any unique Products.", vbCritical + vbOKOnly
Exit Sub
End If

What is important to notice here is how the Table and Fields have been identified using square brackets unlike traditional SQL where we just provide the name, also the table name has to be suffixed with a $ symbol at the end.

As I have suggested earlier, one entire sheet will be treated as one single table, so if you have multiple datasets that were currently organized within one sheet you may have to create multiple sheets to store that data to be able to use them as tables. This would also make maintenance of data easier.

Using Excel SQL to consolidate two sheets in to one

Many people ask, how to consolidate 2 or more sheets which have the similar data. Well I would have adopted this method and wrote a simple query as below.


SELECT ID, FirstName, MiddleName, LastName, Age, DOB From [Table1$]
UNION ALL
SELECT ID, FirstName, MiddleName, LastName, Age, DOB From [Table2$]

This would allow me to use both the sheets as one table and fetch all of my data into a new sheet.

    Hi Chandoo,

    your recent postings include only Excel 2007 templates. Unfortunately the company I work at still runs Excel 2003. Is it possible to get your awesome files in other excel version as well?

    Thanks so much for your great excel stuff!

  2. Stelios Tserkezis says:

    Is it possible to do this for shifts with hours instead of days? To organise a three shift day?

    Thanks in advance,

    Stelios

  3. MASTHAN says:

    In my organization there are 45 employees i need split then into three shifts ex:A shift:14,B shift:14,C shift:14 and week off:3 kindly help me on this.

  4. Hui... says:

    @Masthan

    You need to understand what rules your company has for the various shifts / roster combinations

  5. Georges Lacombe says:

    Chandoo, I once did a shift control spreadsheet for my team. I put one person in each line, the columns were the days. I put a shift code in each cell indicating in which shift that person should work, or if the person were out that day. I have two codes for being out. One is for vacations and one is to compensate days worked in weekends. This way I was able to count how many persons I have in each shift, how many were on vacations and how many were out compensating (that's the term we use here) weekend worked hours.
    Later I included the possibility of a person be in two lines one for normal hours other for overtime. This is mainly used for planning purposes. If you would like I can send you an example. The only problem of this spreadsheet is that we don't have a person view, only this consolidated view.

    • Chuck Vaughan says:

      Hi George, I would like to have a copy of your spreadsheet if you can share it.
       
      Thanks in advance, Chuck   

  6. Idan says:

    Hi Chandoo,

    Where is the code located ? is it VBA ? If so , how do you hide it ? Or it is .NET ?

    Thx

  7. Hui... says:

    @Idan
    .
    No VBA or code, it is all done with Mirrors.
    Only Joking,
    .
    But there is no VBA or code,
    It is all done with Named Formulas and Lookups.
    Have alook at the cells in the calander area and Named Formulas in the Formulas, Name Manager Tab.

  8. Anand Sant says:

    How can i calculate between two or more different workbooks? Please, reply me as early as possible.

    • Hui... says:

      @Anand
      Open the workbooks you want to link to
      Start a formula = and click and change between workbooks as required.
      You can use the View, Switch window menu to change workbooks mid formula

      The format for using workbooks is
      =[Workbook.xlsm]Sheet1!$A$1
      or
      =SUM('[Book2.xls]Sheet1'!$A$1:$D$10)
      etc

    Dear chandoo,

    Try many way to download still can't access. Any way we want to try out 3 shifts with 3 guys in a group .eg Group A Morn, Group B Night and Group C Rest. And every each group must work on sunday to take turns. In fact we are security teams so that's why sunday is required to work. Pls guide and show how to put in the working calendar. Thank you in advance.

  15. Veronica Burggren says:

    I've been trying to copy and/or recreate this to use in a workbook I'm doing for the transportation department I'm working for. I need to have the calendar on the first sheet in my document (it has graph's from data on another sheet). I'm trying to use it to track (with the conditional formatting) accidents and injuries. I've redone the conditional formatting to do 4 different accident types (no injury, near miss, OSHA recordable injury and work loss injury), but when I enter the formula's you have in the calendar portion where it says "DateOfFirst-FirstWeekDay" I can't figure out how you did that. Are you able to help?

  16. Pipin Fantom says:

    I would like to use Excel to solve the following problem for a community work. I want to create a Driver schedule for a given month from a pool of volunteers for a community service. Each of these volunteers can drive only on specific days in a week. I would like to populate the driving schedule for each weekday with primary, secondary and tertiary drivers in a random fashion so that I do not overburden one person. I would greatly any help you can provide.
