I'm trying to analyze my Firestore data in Google Data Studio. I have successfully imported my data from BigQuery to Google Data Studio, but I'm not unable to use it.
Here is my JSON format in GDS :
{
"document_name": "projects/path",
"document_id": "01ASsoYefmYy4h8mGTPWzt5d5Xw1",
"timestamp": "1970-01-01 00:00:00 UTC",
"event_id": "",
"operation": "IMPORT",
"data": "{\"mail\":\"[email protected]\",\"creationDate\":1602011942852,\"initialized\":true,\"languageCode\":\"en\"}"
}
I'm trying to use the creationDate or the mail as field but I'm unable to create a field with this because this is a stringified JSON. I tried to find a solution with formula, without success.
How to exploit field in stringified JSON in Google Data Studio ?
Thanks
I'v finally found a solution : apply a schema view to my data field.
