InfluxDB 2.x: CSV

Import CSV-file directly with Influx-CLI (InfluxDB 2.x)

influx write -b <YOUR_BUCKET> -f <YOUR_CSV>.csv -o <YOUR_ORG> -t <YOUR_TOKEN>

Work with a CSV in InfluxDB 2.x Explorer (from am exported query)

You can export queried data directly from InfluxDB 2.x Explorer with the button near the "Submit" button.
In this example, I show you how to easy work with exported CSV data without import it to your buckets

Exported data from InfluxDB 2.x Explorer:

Use the exported data (Explorer Query): You only have to use import "csv" and create a variable with the CSV-data in it and load the csv with csv.from(csv: csvData).

import "csv" //import the csv library

csvData = "
#group,false,false,false,false,false,false,false,false,false,false
#datatype,string,long,dateTime:RFC3339,dateTime:RFC3339,dateTime:RFC3339,string,string,string,double,double
#default,_result,,,,,,,,,
