@adityavighne , I added this number to a new power bi table(enter data) and was able to create a new custom column in power query

let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjQzNgACCyNzIKkUq4MhEgsA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", Int64.Type}}),
#"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each #datetime(1970, 1, 1, 0, 0, 0) + #duration(0, 0, 0, [Column1]/1000))
in
#"Added Custom"

@adityavighne , Try a new column power query

#datetime(1970, 1, 1, 0, 0, 0) + #duration(0, 0, 0, [timestamp]/1000)

or

#datetime(1900, 1, 1, 0, 0, 0) + #duration(0, 0, 0, [timestamp]/1000)
