Working with Sharepoint List Data

[priyaa]

Hello All, I am working with importing sharepoint list data in power BI. I am stuck with two issues:

1) Not all my column names are coming properly. For few of them the length is reduced by few letters.

2) Why do I see O_DATA prefix with all my column names? 

I have created another mapping sheet to merge the data and because of both these issues I am unable to complete my file. Please help.

Hi @priyaa ,

Is this problem solved?

No @Icey still struggling. Looks like in sharepoint column names were changed/ overwritten for new names but when pulling this backend list in Power BI is still fetching the old names so the mismatch. This is one of the reason i could see . for now i have creating a manual mapping but yeah need a solution for this and working towards understanding the logic

@priyaa is that O_Data showing when you expanded the column from the merged table, if yes, on your expand step there is an option called,  use original name as prefix,  uncheck that option.

I would ❤ Kudos if my solution helped. 👉 If you can spend time posting the question, you can also make efforts to give Kudos whoever helped to solve your problem. It is a token of appreciation!

Hello @parry2k Thank you for taking time out to respond. No this is not coming while merging the data , the moment i import sharepoint list data i see this o_data being prefixed to all columns and also few of my column names are shportened.

Hi @priyaa ,

Please try this:

I'll presume you have already brought in your SharePoint List into Power Query.

Create a new query called RealNames using the OData connector and the Odata query as I defined before. This will bring you a table with columns InternalName and Title (aka RealName).  Transform this into a list or records, then the records into lists.  The items in this final list become the name-value pairs for your rename operation.

let
Source = OData.Feed("https://xxx.sharepoint.com/sites/your site/_api/web/lists/GetByTitle('your list')/Fields?$select=Tit...", null, [Implementation="2.0"]),
recs = Table.ToRecords(Source),
lsts = List.Transform(recs, each Record.ToList(_))
in
lsts

Then back in your query where you brought in the SharePoint list, append this line:

= Table.RenameColumns(#"your previous step name", RealNames, MissingField.Ignore)

This will replace the names of any column whose internal name matches and ignore the others.
