QUICK SYNC EXAMPLE

import assert from "node:assert";
import { generate, parse, transform, stringify } from "csv/sync";

// Run the pipeline
const input = generate({ seed: 1, columns: 2, length: 2 });
const rawRecords = parse(input);
const refinedRecords = transform(rawRecords, (data) =>
  data.map((value) => value.toUpperCase())
);
const output = stringify(refinedRecords);
// Print the final result
assert.equal(output, `OMH,ONKCHHJMJADOA
D,GEACHIN
`);


QUICK STREAM PIPE EXAMPLE

// Import the package
import * as csv from 'csv';

// Run the pipeline
csv
  // Generate 20 records
  .generate({
    delimiter: '|',
    length: 20
  })
  // Transform CSV data into records
  .pipe(csv.parse({
    delimiter: '|'
  }))
  // Transform each value into uppercase
  .pipe(csv.transform((record) =>
    record.map((value) =>
      value.toUpperCase()
