Excel & CSV Viewer

Open and read XLSX, XLS, CSV and ODS spreadsheets right in your browser, switch between sheets and scroll the data as a clean table, with no Excel install needed. Parsed locally; nothing is ever uploaded.

Your spreadsheet renders here as a table you can scroll.

How it works

The workbook is parsed with the SheetJS engine, which reads Excel, CSV and OpenDocument formats. Each sheet is turned into rows and cells and drawn as an HTML table.

Your file is read and displayed entirely in your browser, nothing is ever uploaded.

What this does

An Excel & CSV viewer opens XLSX, XLS, CSV, and ODS spreadsheets as a clean table in your browser — no Excel install needed.

How to use it

  1. Open a spreadsheet file.
  2. Switch between sheets if there are several.
  3. Scroll the data as a table.
  4. Copy the values you need.

How it works

The workbook is parsed locally in your browser, so nothing is uploaded. For speed the table shows the first 1,000 rows; the status line gives the true total.

Example

A multi-sheet sales.xlsx opens with a tab for each sheet.

Frequently asked questions

Which file types can I open?

Excel workbooks (.xlsx, .xls), comma-separated files (.csv) and OpenDocument spreadsheets (.ods). Multi-sheet workbooks let you pick which sheet to view.

Can I edit or save changes?

This is a viewer, it displays the data so you can read and copy it. It does not write changes back to the file.

Is there a row limit?

For speed the table shows the first 1,000 rows of a sheet; the status line tells you the total when a sheet is larger.

Is my spreadsheet uploaded?

No. Everything is calculated locally in your browser.
