Excel-to-Web Viewer — view, search & export spreadsheets on any tablet

About this tool

A lightweight, fully client-side spreadsheet viewer that turns any Excel or CSV file into a clean, searchable, tablet-friendly table — no backend, no accounts, no build step. Upload by drag & drop, then search across all rows, sort columns, apply per-column filters, switch between sheets, and optionally edit cells. Export your filtered view back to CSV or XLSX in one click. Just open index.html or drop it on any static host.

Good to know

Runs entirely in the browser — there is no backend, cloud sync, multi-user support, or saved server state. Everything stays on the user's device, which is great for privacy but means files aren't shared between devices automatically. Very large spreadsheets (tens of thousands of rows) are limited by browser performance. Built on the well-known SheetJS library (loaded via CDN with an integrity hash).
