From now on all Excel object methods and properties will be available once an Excel variable is created inside the Microsoft Access VBA code.
This technique is called early binding, data types are known in advance but checking these references is not mandatory. If those references are not set a late binding technique is being used but it will make development more difficult as the code editor intellisense will not show the properties and methods, deep documentation reading will be required.
A common approach is to use the reference while developing and removing it when finished, the unknown constants must then be replaced by their corresponding integer values. We will not get into much more detail but it is important to be aware these references are not mandatory, they just make life easier. Once the reference to Excel is created we can declare variables types defined there. We will need to declare three variables. The steps involved in the load process can be described as follows.
The required code for the entire process is the following. We will add extensive comments on all lines, please check them bellow in green. Dim xlApp As Excel. Dim xlWb As Excel. Dim xlWs As Excel. Open varfile. Cells intLine, 2. Cells intLine, 7. The insert statement must have the sequence present in the destination table and is obtained by concatenating values per each line presented in the Excel file while iterating.
Cells intLine, 1. Loop Until IsEmpty xlWs. Once the loop stops the steps after close the open workbook, quit excel and clean the memory references to the created objects.
As mentioned before, this is not the only approach to import Excel data, it is possible to create linked tables and, to import data into Microsoft Access, the reader should also consider the DoCmd. TransferDatabase method as well. Linked tables can make use of connectivity drivers so they may not point only to databases, it is even possible to create a linked table to a text file.
Some relevant examples related to the IN clause can be found over here. To run a query in Access pulling data from an Excel file a similar solution to the following one can be used.
Also, when dealing with SQL statements built dynamically it is very important to handle possible null values, replacing them by default values or even forcing the null value insert. If a value can be null the variable needs to be of type Variant to store it and then use it in the built insert statement.
Thanks for reading about how to import excel into Access. Leave a comment if you have any questions on how to import excel into access. Hi, thanks a lot for the code. I managed to use the first part with the file picking.
However, the second one was more difficult. Is it possible to send me the code that I should use for this purpose? Thanks and regards, Susy. Hi Susy, Can you be a bit more specific with what you are trying to accomplish at this point?
Hi ededic87, I would like to import some data to my database via Excel without passing through the Access form I created. As I understood, your code is deleting all data in the database and then loads the entire data from the Excel file. I would like to only complete the data that I already have in my database. Yes using a linked table to an excel file is a possible solution to insert rows into a table linked or not.
The first part regarding the file picker worked perfectly. The next part, not so much. I have my Excel source file Import Test. I want to import all contents of the source file worksheet into the destination table not just columns A, B, and G. This function, when run, will create a new table called Friends and fill it with data stored in the table1. Below is a screen of what my database looks like after the function has been run:.

Importing Data into Microsoft Access using VBA You might be wondering why you would want to use VBA code to import data while you have so many other options available when doing it the visual way.
Well, there are two main reasons: Importing data through VBA code enables you to work with a variety of formats that is not available when you do it using the visual interface such as delimited text in a text file or data in a word table. On a more practical level, if you need to make the same import every time, then simply creating a function to do the job for you will make the process faster and easier as opposed to going through the import wizard every time.
The data can be arranged in two ways: Fixed width format - all the fields are the same size Delimited format - the fields are separated by a special character, such as a comma or a tab.
