CSV data.

Supports anonotated CSV or raw CSV. Use mode to specify the parsing mode.


File path of the CSV file to query.

The path can be absolute or relative. If relative, it is relative to the working directory of the fluxd process. The CSV file must exist in the same file system running the fluxd process.


is the CSV parsing mode. Default is annotations.

Available annotation modes

  • annotations: Use CSV notations to determine column data types.
  • raw: Parse all columns as strings and use the first row as the header row and all subsequent rows as data.

import "csv"

csv.from(file: "path/to/data-file.csv")

Query raw data from CSV file

import "csv"

The future of Flux

Flux is going into maintenance mode. You can continue using it as you currently are without any changes to your code.

Flux is going into maintenance mode and will not be supported in InfluxDB 3.0. This was a decision based on the broad demand for SQL and the continued growth and adoption of InfluxQL. We are continuing to support Flux for users in 1.x and 2.x so you can continue using it with no changes to your code. If you are interested in transitioning to InfluxDB 3.0 and want to future-proof your code, we suggest using InfluxQL.
