Change columns name
Remove the #"Changed Type" step.
If you still need to type your data, then there are various ways to do it dynamically, depending on your specific situation and requirements.
Thanks,

Can you tell me how or refer to specific link to learn about it?
A typical example is to create a list with column names and the required types (this is actually a list of lists) and use that as second argument to function Table.TransformColumnTypes.
In this example, Table1 has 3 columns with a whole number, text and date. The query will still run if column names are adjusted.
let
Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
ColumnNames = Table.ColumnNames(Source),
ColumnTypes = {Int64.Type, type text, type date},
TransformSpecs = List.Zip({ColumnNames,ColumnTypes}),
#"Changed Type" = Table.TransformColumnTypes(Source,TransformSpecs)
in
#"Changed Type"
In the "hard coded" version you can also recognize the list of lists as second argument:
let
Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
#"Changed Type" = Table.TransformColumnTypes(Source,{{"ID", Int64.Type}, {"Text", type text}, {"Date", type date}})
in
#"Changed Type"
Awesome
Thanks!
