I am trying to edit the source of one of my queries using VBA. This is what I have so far: Dim mFormula As String mFormula = _ "let Source = Excel.Workbook(File.Contents(wbname), null, true) in Source" query1 = ActiveWorkbook.Queries.Add("LATEST", mFormula) I set wbname previously in my code. "LATEST" is already added, instead of delete it and read it, I would just like to change the source. Is this possible? You can use ActiveWorkbook.Queries.Item to get the query you want and use the Formula property to update the query's formula, like so: ActiveWorkbook.Queries.Item("LATEST").Formula = "let

In Power Query, I can download data from Web using the Web.Contents function, but there's an api that required the request to contains multipart/form data in the following format "__rdxml"=<*Some data*> So how do you do this using the Web.Contents function? I tried, doing ... PostContent = "__rdxml=<*Some data*>", Source Web.Contents(url,Content=Text.ToBinary(PostContent)) ... But server response with 400 Bad Request . I checked the raw request with Fiddler, it seem like the request is not sending with content-type=multipart/form-data header. I tried manually adding the content-type header

I want to get a value from the previous row. I tried the following code as suggested in this post : Table.AddColumn(#"Added index", "custom column", each {[Index]-1}[column name]) But it throws this error: Cannot use field access fot type List Please help, what am I doing wrong? The error comes because {[Index]-1} without anything before it is a list value, but instead you want to index into a row of a table with this syntax: MyTable{index} That looks like: = Table.AddColumn(#"Added index", "custom column", each #"Added index"{[Index]-1}[My Column]) 来源： https://stackoverflow.com/questions
