Often we look for the documentation of a function or we even look for a function. We may use Microsoft documentation (https://docs.microsoft.com/fr-fr/power-query/). But there is an other way much more comfortable for my needs: access to M functions documentation within Power Query
How to
- Add a blank query and name it ‘Shared’
- Open the advanced editor
- Copy this code and close advanced editor
let
Source = #shared,
#"Converted to Table" = Record.ToTable(Source),
#"Sorted Rows" = Table.Sort(#"Converted to Table",{{"Name", Order.Ascending}})
in
#"Sorted Rows"
Then, you get a list of M functions and constants. Click on a function to get details (don’t click on the word ‘Function’)
You get many information including description, parameters, examples, …
Of course, you can filter the names just like you do with any other table
Don’t forget to remove filter before applying a new one because they are cumulative !
So, in this way, you always have M functions documentation available no matter if you have an internet connection.
