Combining Columns or replacing
I'd really call that doing it from the Ribbon scott_Abaana - you want several if/then/else constructs. If you can do nested IF() functions in Excel (or IFS()) then you can do this.
From the ribbon, go to Add Columns, then Custom Column, and type in this formula:
if [FREQ] = "Cash" then [Amount] else if [FREQ] = "Yearly" then [Amount] else if [FREQ] = "Monthly" then [Amount] * 12 else if [FREQ] = "Quarterly" then [Amount] * 4 else nullSo intead of creating all of the columns, you just do the math on the [Amount] field.
The if/then/else construct is a bit different than Excel.
- the keywords if, then, and else are always lowercase
- All three are required. Excel lets you leave the last one out and you can do =IF(A1=5,3) and that will return a blank if A1 doesn't equal 5 in Excel. In Power Query, if [Field] = 5 then 3 will return an error because else is missing. I used else null for your final answer, but you can return the 9999999 if you want.
Here is your workbook back. Look at my Single if then else query.
Hello scott_Abaana
your approach is kinda tedious. You can use a Table.ReplaceValue to do everything in one step. I made a quick example for you
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclTSUXICYmcgdgFiIwMjA6VYHWwShpZKsbEA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [A = _t, B = _t, C = _t, D = _t, E = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"A", type text}, {"B", type text}, {"C", type text}, {"D", type text}, {"E", Int64.Type}}),
ChangeE = Table.ReplaceValue
(
#"Changed Type",
each [E],
(row)=>
let
F = if row[E]=2020 then "twentytwenty" else "twentynineteen",
G = if row[E]=2020 then "laterthen2019" else "laterthen2018",
H = if row[E]=2020 then "higher" else "lower",
Combine = if row[E]=2020 then Text.Combine({F,G,H}) else Text.Combine({H,F,G})
in
Combine,
Replacer.ReplaceValue,
{"E"}
)
in
ChangeE

Jimmy801 Yeah it is tedious, (hence the Question) 🙂
This type of problem comes up a lot in my current Build.
Will have a look at the code and see how it works for me.
Many thanks.
Ps is there a built option in PQ that does the same/similar thing?
