csv.from() function

The csv.from() function retrieves data from a comma-separated value (CSV) data source. It returns a stream of tables. Each unique series is contained within its own table. Each record in the table represents a single point in the series.

Function type: Input

import "csv"

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

// OR

csv.from(csv: csvData)

Parameters

file

The 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 influxd process. The CSV file must exist in the same file system running the influxd process.

InfluxDB Cloud does not support the file parameter.

Data type: String

csv

Raw CSV-formatted text.

CSV data must use Annotated CSV syntax and include all annotation rows. For more information, see Annotated CSV.
