I/O guide

Functions

Read and write JSON

json::read

json::read(path: String) -> DataFrame

Reads a JSON file in one of the formats supported by the bundled JSON plugin and returns its records as a DataFrame. The plugin owns the input format details; this function does not take a schema or parsing options.

json::write

json::write(df: DataFrame, path: String) -> Int

Writes the DataFrame to the given path and returns the number of rows written.

Example

Read, transform, and write

After reading, JSON data is an ordinary table and can be filtered or projected before writing.

import "json";

let events = json::read("data/events.json");
let recent = events[filter active, select { id, category, timestamp }];
let rows_written = json::write(recent, "out/active-events.json");
