Quickstart - Graphy SDK

@graphysdk/data-import-utils converts CSV, TSV, and spreadsheet files into the Data structure expected by @graphysdk/core.

Installation

npm install @graphysdk/data-import-utils @graphysdk/core

yarn add @graphysdk/data-import-utils @graphysdk/core

pnpm add @graphysdk/data-import-utils @graphysdk/core

Parse a CSV

import { fromCSV } from '@graphysdk/data-import-utils';

const data = fromCSV('Name,Revenue\nAcme,1000\nGlobex,2000');
// { columns: [{ key: 'c1', label: 'Name' }, ...], rows: [...] }

Parse a Spreadsheet

import { fromXLSX } from '@graphysdk/data-import-utils/xlsx';

const buffer = await file.arrayBuffer();
const data = await fromXLSX(buffer, { sheet: 'Revenue' });

Parse from Disk (Node.js)

import { fromFile } from '@graphysdk/data-import-utils/file';

const data = await fromFile('sales.csv');

fromFile auto-detects the format from the file extension. See File for details.

Parse from URL

import { fromURL } from '@graphysdk/data-import-utils/url';

const data = await fromURL('https://example.com/sales.csv');

fromURL fetches a remote file and auto-detects the format from the URL path extension. See URL for details.
