How to group durations

[TimR]

Hi, 

I'm looking for a way to group time durations.

The raw data contains durations in format h:mm:ss:xxx :

Duration action

1:01:07.560

0:26:01.123

0:00:14.330

0:00:11.253

0:04:12.287

I want to add a grouped duration based on these groups:

0 - 30 sec

30s - 1m

1m - 2m

2m - 5m

5m - 15m

15m - 30m

30m - ∞

Desired result:

Duration action	Grouped duration
1:01:07.560	30m - ∞
0:26:01.123	15m - 30m
0:00:14.330	0 - 30 sec
0:00:11.253	0 - 30 sec
0:04:12.287	2m - 5m

Hope that there is someone that could help..

Many thanks in advance!!

Cheers,

Tim

Hello @TimR 

you can ues nested if-statements like this

if [Duration action]<#duration(0,0,0,31) then "0 - 30 sec" else if [Duration action]<#duration(0,0,1,1) then "30s - 1m" else "etc."

here a complete example

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("TYnJCcBADMR68TsMM/Yewa0Y999G9hFCQB9JVabkYWMuWl9lTF8nQR6vk6mBCP5c8Pn9kXL4va37AQ==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Duration action" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Duration action", type duration}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Grouped duration", each if [Duration action]<#duration(0,0,0,31) then "0 - 30 sec" else if [Duration action]<#duration(0,0,1,1) then "30s - 1m" else "etc.")
in
    #"Added Custom"

Copy paste this code to the advanced editor in a new blank query to see how the solution works.

Final question 🙂
There are cells which do not contain a duration. This results in an error. How can I prevent the error and keep the Grouped duration empty if the duration action is empty?

Hello @TimR 

use this code instead

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("TYnJCcBADMR68TsMM/Yewa0Y999G9hFCQB9JVabkYWMuWl9lTF8nQR6vk6mBCP5c8Pn9kXL4va37AQ==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Duration action" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Duration action", type duration}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Grouped duration", each try if [Duration action]<#duration(0,0,0,31) then "0 - 30 sec" else if [Duration action]<#duration(0,0,1,1) then "30s - 1m" else "etc." otherwise null)
in
    #"Added Custom"
