从 URL POWER QUERY 获取文件名

Question

I am trying to query multiple csv files from a URL using power query in excel. I am able to download the content. But I want to add another column with the filename.

Can anyone shed some light on how I can do it?

Here is a sample URL.

https://www.punters.com.au/form-guide/spreadsheet-1175858

The filename of this link would be "20210716-geelong-r01.csv". Opening the link will download the file with this filename.

Query I have so far below.

let
    Source = Table.FromColumns({Lines.FromBinary(Web.Contents("https://www.punters.com.au/form-guide/spreadsheet-1175858"), null, null, 65001)}),
    #"Split Column by Delimiter" = Table.SplitColumn(Source, "Column1", Splitter.SplitTextByDelimiter(",", QuoteStyle.Csv), {"Column1.1", "Column1.2", "Column1.3", "Column1.4", "Column1.5", "Column1.6", "Column1.7", "Column1.8", "Column1.9", "Column1.10", "Column1.11", "Column1.12", "Column1.13", "Column1.14", "Column1.15", "Column1.16", "Column1.17", "Column1.18", "Column1.19", "Column1.20", "Column1.21", "Column1.22", "Column1.23", "Column1.24", "Column1.25", "Column1.26", "Column1.27", "Column1.28", "Column1.29", "Column1.30", "Column1.31", "Column1.32", "Column1.33", "Column1.34", "Column1.35", "Column1.36", "Column1.37", "Column1.38", "Column1.39", "Column1.40", "Column1.41", "Column1.42", "Column1.43", "Column1.44", "Column1.45", "Column1.46", "Column1.47", "Column1.48", "Column1.49", "Column1.50", "Column1.51", "Column1.52", "Column1.53", "Column1.54", "Column1.55", "Column1.56", "Column1.57", "Column1.58", "Column1.59", "Column1.60", "Column1.61", "Column1.62", "Column1.63", "Column1.64", "Column1.65", "Column1.66", "Column1.67", "Column1.68", "Column1.69", "Column1.70", "Column1.71", "Column1.72", "Column1.73", "Column1.74", "Column1.75", "Column1.76", "Column1.77", "Column1.78", "Column1.79", "Column1.80", "Column1.81", "Column1.82", "Column1.83", "Column1.84", "Column1.85", "Column1.86", "Column1.87", "Column1.88", "Column1.89", "Column1.90", "Column1.91", "Column1.92", "Column1.93", "Column1.94", "Column1.95", "Column1.96", "Column1.97", "Column1.98", "Column1.99", "Column1.100", "Column1.101", "Column1.102", "Column1.103", "Column1.104", "Column1.105", "Column1.106", "Column1.107", "Column1.108", "Column1.109", "Column1.110", "Column1.111", "Column1.112", "Column1.113", "Column1.114", "Column1.115", "Column1.116", "Column1.117", "Column1.118", "Column1.119", "Column1.120", "Column1.121", "Column1.122", "Column1.123", "Column1.124", "Column1.125", "Column1.126", "Column1.127", "Column1.128", "Column1.129", "Column1.130"}),

Thanks in advance for any help.

Answer 1

Use this formula in Power Query

= Table.TransformColumnTypes(#"Split Column by Delimiter",{{"Column1.1", type text}, {"Column1.2", type text}, {"Column1.3", type text}, {"Column1.4", type text}, {"Column1.5", type text}, {"Column1.6", type text}, {"Column1.7", type text}, {"Column1.8", type text}, {"Column1.9", type text}, {"Column1.10", type text}, {"Column1.11", type text}, {"Column1.12", type text}, {"Column1.13", type text}, {"Column1.14", type text}, {"Column1.15", type text}, {"Column1.16", type text}, {"Column1.17", type text}, {"Column1.18", type text}, {"Column1.19", type text}, {"Column1.20", type text}, {"Column1.21", type text}, {"Column1.22", type text}, {"Column1.23", type text}, {"Column1.24", type text}, {"Column1.25", type text}, {"Column1.26", type text}, {"Column1.27", type text}, {"Column1.28", type text}, {"Column1.29", type text}, {"Column1.30", type text}, {"Column1.31", type text}, {"Column1.32", type text}, {"Column1.33", type text}, {"Column1.34", type text}, {"Column1.35", type text}, {"Column1.36", type text}, {"Column1.37", type text}, {"Column1.38", type text}, {"Column1.39", type text}, {"Column1.40", type text}, {"Column1.41", type text}, {"Column1.42", type text}, {"Column1.43", type text}, {"Column1.44", type text}, {"Column1.45", type text}, {"Column1.46", type text}, {"Column1.47", type text}, {"Column1.48", type text}, {"Column1.49", type text}, {"Column1.50", type text}, {"Column1.51", type text}, {"Column1.52", type text}, {"Column1.53", type text}, {"Column1.54", type text}, {"Column1.55", type text}, {"Column1.56", type text}, {"Column1.57", type text}, {"Column1.58", type text}, {"Column1.59", type text}, {"Column1.60", type text}, {"Column1.61", type text}, {"Column1.62", type text}, {"Column1.63", type text}, {"Column1.64", type text}, {"Column1.65", type text}, {"Column1.66", type text}, {"Column1.67", type text}, {"Column1.68", type text}, {"Column1.69", type text}, {"Column1.70", type text}, {"Column1.71", type text}, {"Column1.72", type text}, {"Column1.73", type text}, {"Column1.74", type text}, {"Column1.75", type text}, {"Column1.76", type text}, {"Column1.77", type text}, {"Column1.78", type text}, {"Column1.79", type text}, {"Column1.80", type text}, {"Column1.81", type text}, {"Column1.82", type text}, {"Column1.83", type text}, {"Column1.84", type text}, {"Column1.85", type text}, {"Column1.86", type text}, {"Column1.87", type text}, {"Column1.88", type text}, {"Column1.89", type text}, {"Column1.90", type text}, {"Column1.91", type text}, {"Column1.92", type text}, {"Column1.93", type text}, {"Column1.94", type text}, {"Column1.95", type text}, {"Column1.96", type text}, {"Column1.97", type text}, {"Column1.98", type text}, {"Column1.99", type text}, {"Column1.100", type text}, {"Column1.101", type text}, {"Column1.102", type text}, {"Column1.103", type text}, {"Column1.104", type text}, {"Column1.105", type text}, {"Column1.106", type text}, {"Column1.107", type text}, {"Column1.108", type text}, {"Column1.109", type text}, {"Column1.110", type text}, {"Column1.111", type text}, {"Column1.112", type text}, {"Column1.113", type text}, {"Column1.114", type text}, {"Column1.115", type text}, {"Column1.116", type text}, {"Column1.117", type text}, {"Column1.118", type text}, {"Column1.119", type text}, {"Column1.120", type text}, {"Column1.121", type text}, {"Column1.122", type text}, {"Column1.123", type text}, {"Column1.124", type text}, {"Column1.125", type text}, {"Column1.126", type text}, {"Column1.127", type text}, {"Column1.128", type text}, {"Column1.129", type text}, {"Column1.130", type text}})

It is same as splitting column with delimiter 'comma'

You can acheive this using custom column
