DIF to JSONDIF

Data Interchange Format.

A vintage format created for VisiCalc. Still found in archival data exchange. TabularJS handles headers, labels, and comments.

Feature support

Example

const result = await tabularjs('archive.dif');

Why TabularJS for DIF?

• No external parser dependencies — faster installs, smaller bundles.
• Works identically in Node.js and modern browsers.
• Output is shape-compatible with Jspreadsheet — render parsed data in a live workbook with one call.
