How to Import Specific Sheets from Multiple Excel Files in a SharePoint Folder for PowerBI Projects
In the data-driven world of today, PowerBI has emerged as a go-to tool for transforming raw data into insightful visuals. However, the initial step of importing data, especially when dealing with multiple Excel files stored in SharePoint folders, can be a challenging process. This article will dive deep into the intricacies of efficiently importing specific sheets from several Excel files within SharePoint folders into PowerBI. We'll elucidate how the FolderPath
and file arguments should be handled for a hassle-free integration, ensuring you avoid common pitfalls that can trip up even experienced data analysts.
The Challenge Explained
When working with PowerBI and SharePoint, one common challenge is ensuring the correct arguments and paths are utilized when importing data. A frequent mistake is misunderstanding how the FolderPath
argument should be structured or what values are being passed to the function.
Understanding FolderPath
and SharePoint.Files
Initially, when connecting PowerBI to SharePoint to import Excel files, you need to specify the FolderPath
. This is a crucial step, but often, there's confusion about what exactly needs to be provided.
- First Line
FolderPath
: This should be the root of the SharePoint site or sub-site hosting the file you want to access. For instance, if your excel files are stored on a SharePoint site, your FolderPath
should point to the site's URL without specifying the path to the specific file.
Source = SharePoint.Files("https://tenantname.sharepoint.com/sites/thesite", [ApiVersion = 15])
- TheFile
FolderPath
: When specifying the path for the individual file, this FolderPath
is more detailed and formatted like a URL, guiding PowerBI through the SharePoint folders to the desired file.
TheFile = Source{[Name="Workbook.xlsx", #"Folder Path"="https://tenantname.sharepoint.com/sites/thesite/Reports/2016/November/Finance Committee/"]}[Content]
Step-by-Step Guide to Importing Your Files
Navigating through SharePoint folders and files can be simplified with the following steps, ensuring you correctly fetch the exact sheets you need without extraneous data complication.
Step 1: Connect to SharePoint Site
Initiate by connecting PowerBI to your SharePoint site using the root URL as the FolderPath
. This action creates a connection, returning a table of all the files on the site.
Step 2: Specify the File and Sheet
After obtaining a list of files, narrow down to the specific Excel file and further to the exact sheet you wish to import. This is done by specifying the detailed FolderPath
and the file's name. Using PowerQuery, transform the binary Content
returned into something PowerBI can use.
