Parameter case sensitivity|Power Query|Excel Forum|My Online Training Hub

Hello,

I'd be grateful for some PQ Parameter help, please.

I'm planning to distribute a workbook that applies a number of queries based on files in a Dropbox folder, to a number of teams. Because the teams will have different Dropbox paths and may give their source workbooks different names, I've set up a Parameter table to enable each team to set up their particular paths and names. The relevant M-code is:

Source = Folder.Files(#"fnGetParameter"("Dropbox path")),
#"Filtered Rows" = Table.SelectRows(Source, each [Name] = #"fnGetParameter"("Visit tracker name"),

So far, so good, but I'd like to make the parameter function (fnGetParameter) case-insensitive so that it will work regardless of how the parameter is entered in the table. In other words, if the source workbook is called Visits.xlsx, I want it still to work if the parameter is entered as "visits.xlsx" etc. The code for the function is:

let
Source = (ParameterName as text) =>
let
ParamSource = Excel.CurrentWorkbook(){[Name="tblTrackerParameters"]}[Content],
ParamRow = Table.SelectRows(ParamSource, each ([Description] = ParameterName)),
Value=
if Table.IsEmpty(ParamRow)=true
then null
else Record.Field(ParamRow{0},"Value")
in
Value
in
Source

I had thought about using Comparer.OrdinalIgnoreCase, but Table.SelectRows doesn't seem to support it. Can you possibly help?

Thanks very much.

Pieter
