Quick Example

Section titled “Quick Example”

Convert your ISA-JSON datasets into standardized formats instantly:

import { convertIsaJsonToIsaTab, convertIsaJsonToZip } from 'isa4js';


// 1. Convert ISA-JSON data directly to standard ISA-Tab strings
const isaTabResult = convertIsaJsonToIsaTab(isaJsonData);


// 2. Or compile the entire ISA-Tab set straight into a compressed ZIP blob/buffer
const zipArchive = await convertIsaJsonToZip(isaJsonData);
