JSON datetime conversion in power query

[Anonymous]

Hi,

I am looking for 2 clear solutions.

1. Query for JSON string datetime conversion to datetime in PBI.

2. Can a ONE query be executed to convert multiple columns that are currently in JSON string datetime format ?

Thanks in advance for any solutions around this.

Hi @Anonymous , 

If possible, could you please inform me more detailed information (such as your json sample and your expected output)? Then I will try to test this in my enviornment.

Please do mask sensitive data before uploading.

Thanks for your understanding and support.

JSON doesn't have a standardized datetime string format. Are you talking about ISO-8601 ? Maybe show an example of your strings?

And yes, transforms can be applied to multiple columns at the same time.

Hi @lbendlin @dax 

Correct its ISO-8601

attached Screen shot of the data presented in Power BI

iv applied a few different queries but no luck as yet.

Hi @Anonymous , 

You could try @lbendlin 's suggestions and change it like below

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjS1NDI3NDUzAAGl2FgA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [name = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"name", type number}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each #datetime(1970, 1, 1, 0, 0, 0) + #duration(0, 10, 0, [name]/1000)),
    #"Changed Type1" = Table.TransformColumnTypes(#"Added Custom",{{"Custom", type datetime}})
in
    #"Changed Type1"

Those are millisecond epochs.

You can use them as described here:
