How to combine SharePoint List from multiple SharePoint sites
I cannot share the pbix sample but I can provide the explanation of the code:
The code is designed to fetch data from multiple SharePoint lists based on the URLs and list names provided in an Excel file.
The first part of the code reads an Excel file. This Excel file contains a list of SharePoint site URLs and corresponding list names. The Excel.Workbook function is used to load the Excel file, and the Table.RenameColumns function is used to rename the columns to "Site URL" and "List Name".
Next, a custom function named FetchList is defined. This function takes a SharePoint site URL as an argument and returns a table of all lists in the SharePoint site. The SharePoint.Tables function is used to fetch the lists from the SharePoint site.
Finally, a new column named "Custom" is added to the table. For each row in the table, the FetchList function is called with the site URL from that row. The result is a table with an additional column that contains the SharePoint lists for each site URL.
This code is a common pattern in Power Query M language for fetching and combining data from multiple sources based on a list of parameters.
try this one.
let
// Get the list of SharePoint sites and corresponding list names
Source = SharePoint.Tables("https://main.sharepoint.com", [ApiVersion = 15]),
SitesList = Source{[Name="SitesList"]}[Content],
#"Changed Type" = Table.TransformColumnTypes(SitesList,{{"Site URL", type text}, {"List Name", type text}, {"Tenant Name", type text}, {"Site Code", type text}}),
// Add a custom function to fetch data from the corresponding SharePoint list for each SharePoint site
FetchList = (site as text, list as text) =>
let
Source = SharePoint.Tables(site, [ApiVersion = 15]),
List = Source{[Name=list]}[Content]
in
List,
// Add a new column "Custom" to call the custom function for each row
AppendLists = Table.AddColumn(#"Changed Type", "Custom", each FetchList([Site URL], [List Name])),
// Expand the tables from the "Custom" column into rows
#"Expanded Custom" = Table.ExpandTableColumn(AppendLists, "Custom", {"Employee ID", "Name", "Position"}, {"Employee ID", "Name", "Position"}),
// Select only the necessary columns
#"Removed Other Columns" = Table.SelectColumns(#"Expanded Custom",{"Tenant Name", "Site Code", "Employee ID", "Name", "Position"})
in
#"Removed Other Columns"
This script will:
- Fetch the list of SharePoint sites and their corresponding list names from your main SharePoint site.
- For each SharePoint site, it fetches the corresponding SharePoint list.
- It then expands each fetched SharePoint list into rows and appends these rows into the main table.
- Finally, it selects only the necessary columns.
Please replace "Employee ID", "Name", "Position" with your actual column names in the SharePoint Lists. If your lists have different structures, you'll need to modify the script accordingly to accommodate those differences.
Also, please replace "https://main.sharepoint.com" with your main SharePoint site URL and "SitesList" with your actual list name that contains the SharePoint site URLs and corresponding list names.
this is an experimental solution. you need to adjust it.
Hello
Thanks for the solution. I am newbie in Power BI, how to use above mentioned in Power BI?
Happy to help. Kudos will be more appropriated.
Go to power query. Open advanced editor. And try copy paste the code. But you need to adjust the code value with your own value.
Did I help? If yes, hit 👍
