Parsing JSON is not giving all values
I am getting some odd behavior from attempting to expand a column with different JSON strings. Each column can have different strings. It appears that
= Table.TransformColumns(#"Sorted Rows",{{"CustomFields", Json.Document}})
only grabs a certain number of records/rows. I need it to see ALL of them. We have sorted the table such that the problem row at 204 shows up at row 1, and everything works as expected. But I have no control over where this record lies in production. I am scratching my head here. The image below is the newly sorted version.

Hi Anonymous ，
Are you looking for output similar to this? Try unpivoting the expanded columns.Advanced editor:
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WUqiOUQpJLM52SSxJDcnMTTUyiVGyilEyMjAy0TUw0jU0CzEwsAIjPQMDgxglHTTlxijKjSwJKDdCVW6EprxWSUfJUClWJ1oJ6iy/sMQi54zEIhNTsEa4gTBxIwsLqEStAlCvEQV6jSnQa6IUGwsA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [CustomFields = _t, Column1 = _t]), #"Replaced Value" = Table.TransformColumnTypes(Source,{{"CustomFields", type text}, {"Column1", Int64.Type}}), #"Parsed JSON" = Table.TransformColumns(#"Replaced Value",{{"CustomFields", Json.Document}}), #"Expanded CustomFields" = Table.ExpandRecordColumn(#"Parsed JSON", "CustomFields", {"TaskDateTime24", "TaskDateTime23", "TaskDateTime22", "TaskNVarChar45", "TaskNVarChar288"}, {"TaskDateTime24", "TaskDateTime23", "TaskDateTime22", "TaskNVarChar45", "TaskNVarChar288"}), #"Unpivoted Columns" = Table.UnpivotOtherColumns(#"Expanded CustomFields", {"Column1"}, "Attribute", "Value") in #"Unpivoted Columns"If I misunderstood your question, could you tell me what your expected output is?
