What is an XLSX viewer?

An XLSX viewer opens Microsoft Excel spreadsheet files (.xlsx) so you can read rows, sheets, formulas, and charts without buying Excel. With WPS Office, you can view and edit the file on desktop, phone, or online. Double-click a file on desktop, use Sheets in the WPS app on mobile, or open it in your browser with WPS Excel Online.

Why use WPS as your XLSX viewer

Most browser tools only preview a file. WPS opens the spreadsheet, keeps formatting intact, and lets you edit, save, and export when you need more than a quick look.

Open files the Excel way

  • Double-click .xlsx or open from Sheets inside WPS.
  • Row and column grid, sheet tabs, and menus match what Excel users expect.
  • Find data fast with search, filters, and freeze panes.

View more than plain cells

  • Formulas show calculated results. Charts and tables stay in place.
  • Multiple sheets open in one workbook. Switch tabs without reopening the file.
  • Conditional formatting, merged cells, and number formats carry over on most files.

Edit when reading is not enough

  • Change values, add rows, adjust formatting, then save back to .xlsx.
  • Print or export to PDF for sharing read-only copies.
  • Batch workflows live in the full suite, not in a one-file browser preview.

One app for every document type

  • Open Word, Excel, PowerPoint, and PDF in the same install.
  • Stop installing separate viewers for each format.
  • Sync through WPS Cloud when you work across laptop and phone.
