Hi,

I am unable to extract fields from JSON data using textractjsonfields. JSON input data looks like this

[{"Id":42925362566,"UnitId":"254125220221","Direction":201.00,"DriverKeyCode":5257,"EventTypeId":149,"EventTypeDescription":"Start of Speeding","LocalTimestamp":"2018-04-17T09:01:54+03:00","Odometer":1349826,"Position":[49.34381,-18.19258],"Speed":46.00,"UnitOfDistanceCode":"km","StartOfExceptionData":{"Limit":45.0}},{"Id":42963589658,"UnitId":"261321220221","Direction":202.00,"DriverKeyCode":8507,"EventTypeId":150,"EventTypeDescription":"Speeding","LocalTimestamp":"2018-04-17T05:02:03+03:00","Odometer":1349827,"Position":[49.34342,-18.19352],"Speed":46.00,"UnitOfDistanceCode":"km","EndOfExceptionData":{"Limit":45.0,"Maximum":46.0,"Duration":14}},{"Id":42965248569,"UnitId":"261321525654","Direction":158.00,"DriverKeyCode":8565,"EventTypeId":149,"EventTypeDescription":"Start of Speeding","LocalTimestamp":"2018-04-17T05:02:47+03:00","Odometer":542971,"Position":[47.48203,-18.86108],"Speed":46.00,"UnitOfDistanceCode":"km","StartOfExceptionData":{"Limit":45.0}},{"Id":42965588747,"UnitId":"261321220440","Direction":158.00,"DriverKeyCode":4575,"EventTypeId":150,"EventTypeDescription":"Speeding","LocalTimestamp":"2018-04-17T05:03:05+03:00","Odometer":542971,"Position":[47.48280,-18.86287],"Speed":47.00,"UnitOfDistanceCode":"km","EndOfExceptionData":{"Limit":45.0,"Maximum":47.0,"Duration":24}},

Input fields come as

statusCode,

body,

string,

so I have given the output extract fields columns as

Id,

UnitId,
Direction,
DriverKeyCode,
EventTypeId,
EventTypeDescription,
LocalTimestamp,
Odometer,
Position,
Speed,
UnitOfDistanceCode.

Loop xpath query: "/*"

try with XPath - "/" (no *)

and it would be something like:

.-----------+------------+---------+-----------+-----------+-----.
|                           tLogRow_1                            |
|=----------+------------+---------+-----------+-----------+----=|
|Id         |UnitId      |Direction|PositionLat|PositionLon|Speed|
|=----------+------------+---------+-----------+-----------+----=|
|42925362566|254125220221|201      |49.34381   |-18.19258  |46   |
