About & Contact

SheetCraft is a pure front-end Excel toolbox built for data engineers, accountants and operations teams. We turned the 10 most frequent spreadsheet chores — merging, splitting, comparing, cleaning — into single-page tools that work the moment you open them: no sign-up, no queue, no upload. Your files stay in your browser from start to finish.

Privacy-first is an architectural principle here: all computation runs in browser Web Workers on your device. Our servers only deliver static pages and can never touch your file contents.

Feature ideas, bug reports or business inquiries — all welcome:

Working hours: Mon–Fri 9:00–18:00 (Beijing time). Emails are usually answered within 1–2 business days.
