How to connect CSV with SharePoint

This "how-to-connect" documentation will explain the initial configuration of an example connection from CSV to a SharePoint Online List in Office 365. We will be synchronizing data stored in CSV.

 

This guide presupposes that you have installed the Layer2 Cloud Connector and that you are familiar with its basic functionality. The Layer2 Cloud Connector User Documentation will provide you with all necessary information.

1. Configuring CSV

To connect to a CSV file, you must create a connection through the ODBC. This database interface should be already installed in your Windows machine. Press the Windows key and type ODBC. Select System DSN in the opened window and click on Add to create a new connection.

Select the Microsoft Access Text provider and click on Finish.

Give a name to your Data Source Name and select the Directory where the CSV file is located in.

2.1. Creating a new connection

Create a new connection by using the Create New Connection option in the Actions pane (right-hand side). The new connection will appear at the bottom of the Connection Manager List (left-hand side). Click on your newly created connection to open the connection configuration settings.

 

Choose a meaningful name for your connection and replace the current "New Connection" Connection Title with it.

 

Connections to CSV are uni-directional. An initial connection should always be uni-directional to assure that both data entities are identical before switching to bi-directional. Therefore, choose Left to Right as Direction.

2.2. Configuring the Data Entity 1

We will now set up our Data Entities. Go to the data entity “Data Entity 1” to open the configuration settings.

 

Choose a Data Entity Title. It is recommended to give your entities meaningful names to maintain an overview when you decide to set up multiple connections.

 

Select the Data Provider for ODBC from the data provider list. You can search for ODBC by typing into the selection box.

 

Step 2 CSV integration source setup.png

 

For the Connection String, we need the in step 1 mentioned information. You can copy the below connection string and adjust it to match your gathered information. Use the Verify Connection String option to evaluate if the provided connection string is valid.

 

 

DSN=CSV;

 

 

  • "DSN=DSNconnectionname;" this property defines the ODBC connection name we are using. That is the name from the connection we created in the first step.

 

The Select Statement text box is used to define specific data queries. We will be gathering all results from our samplecsv file. You can copy the below select statement and adjust it to match your needs. Save your changes by using the right-hand pane option Save Changes.

 

SELECT * FROM samplecsv.csv

 

Step 2.5 CSV integration connection string setup.png

 

To check if all necessary columns are received, you can use the Preview Data option on the right-hand pane which will provide you with a pop-up window showing your sample data from your CSV entity.

2.3. Configuring the Data Entity 2

We are going to send the data to a custom SharePoint Online list. It's required that you set up this list prior to the next steps. Your list should contain matching columns according to your source entity.

 

Use the left-hand pane to switch to the data entity "Data Entity 2". We will be using the Layer2 SharePoint Provider for this setup. 

 

For more information about the SharePoint provider visit:

https://www.layer2solutions.com/support/cloud-connector-faqs/layer2-csom-sharepoint-ado-net-provider.

 

You can copy the below Connection String which contains the minimum of required properties to connect to your custom SharePoint Online list.

 

URL=https://your_custom_sharepoint_list_url/AllItems.aspx;Authentication=Office365;User=User@domain.com;

 

  • "URL=https://your_custom_sharepoint_url/AllItems.aspx;" this property defines the URL of your custom list that will be addressed.
  • "Authentication=Office365;" this property will determine the authentication method used. Office 365 is the default authentication method to access Microsoft Office 365 / SharePoint Online. This method will not work in case of federation, e.g. ADFS. For further authentication method you can consult the provider specifications linked above.
  • "User=User@domain.com;" this property should describe the user you wish to connect to SharePoint to. 

 

Enter the password that belongs to the user account used in the connection string into the Password field. Save your changes by using the right-hand pane option Save Changes.

 

Step 3 CSV integration target setup.png

 

In the next step, we will configure our mapping settings. Click on the Mappings option on the left-hand pane. If your fields from SharePoint are named identical to the fields from your source system, the Enable Auto Mapping option will match those columns. Disabling this option allows you to match your columns as needed. We enabled auto-mapping in our setup. Save your changes by using the right-hand pane option Save Changes.

2.4. Running your connection

To run your connection switch back to the main connection configuration node and use the Run Now Button located on the bottom of the setup page. The Run Synchronization Toolbox will also display the synchronization process. 

 

Step 5 CSV data integration start.png

 

Below is a data preview of the information we have accessed in our source entity:

This will be the result in our SharePoint Online list after our initial successful synchronization:

See section 3.1 for further information.

3. Hints and known issues

 

3.1. Connection direction

As far as tested, this connection supports uni-directional only.

 

 

3.2. Custom format

 

 

You can also define custom delimiters for your CSV-file. When setting your ODBC connection, click on Options and Define format.

 

CSV define format

Select your CSV-file and under Format define the delimiter type you want to use. The default value is CSV delimited with the ; symbol. You can set almost any other symbol selecting Custom Delimited. Comma symbols should be avoided as described by Microsoft here.
