InfluxDB tagging

I parse CSV file like:

[time],[tag1],[tag2],[data1],[data2],..

I've fluent-bit parse to decode everything correctly to regex groups.

I need to output to influx with tag* keys as tags and data* as fields.
Like:
[measurement from Tag-directive],[tag1]=[tag1.value],[tag2]=[tag2.value] [data1]=[data1.value],.. [time]

Is this true it it cannot be done? Because power of Influx are the tags and indexing the tags to get correct fields values.
