Got a table to check? XLSX Viewer shows it in a tab. It also works as a csv reader and xls file opener. Files stay on your device. XLSX Viewer is a quick xlsx viewer for the browser. It opens spreadsheets in a tab, lets you browse every sheet, search and copy cells, and never sends your files anywhere. Made for the many tables we only need to read: reports, price lists, exports, timetables. ▸ Formats: .xlsx, .xls and .csv ▸ Ways to open: drag and drop, file picker, a link ▸ Downloads: spreadsheet links open in the viewer by themselves ▸ Privacy: files are read on your computer, nothing is uploaded 🔹 Open a File in Seconds Drag a spreadsheet from a folder onto the viewer page, choose one with the file picker, or paste a link. The workbook appears in the XLSX Document Viewer with all its sheets. A file someone just sent you is on screen in seconds. 🔹 Downloads Open by Themselves Click a link to a spreadsheet in webmail, in a chat or on a website: the download is saved as usual, and the file also opens in a viewer tab right away. It acts as an xlsx file opener for every spreadsheet link, with no digging through the Downloads folder. On a site with a sign-in, one click on Allow lets it read files from that site. Prefer the old way? Turn it off in Settings. 🔹 Read Long Tables Comfortably ✓ Sheet tabs switch between the sheets of a workbook ✓ The header row stays on top while you scroll, so you always know which column is which ✓ Search finds a word or a number on the sheet, so a long list of names or order numbers takes seconds to check ✓ Copy cells and paste them into a document, a message or another table 🔹 Private by Design Many people search for an online xlsx viewer and end up uploading payroll or client data to a stranger's server. This XLSX File Viewer reads files locally, inside the browser. The extension has no server of its own, no account and no ads, and it does not track what you open. 🔹 CSV Without the Wall of Commas A bank statement or a store export turns into a neat table with a fixed header. As a CSV Viewer it is handy for checking one column or finding one value, and as a csv opener it skips the import dialogs of big programs. If you were looking for a csv reader online, this one keeps the rows on your computer. 🔹 Old XLS Files Too Accounting systems and archives still produce .xls files. The XLSX Document Viewer shows them like new workbooks, each sheet in its own tab, so it doubles as an XLS File Opener. Paste a link and you can open xls online in a tab without converting anything. To view xls file online from a supplier site, the steps are the same. 🔹 Why a Browser Extension Your mail, chats and shared links already live in the browser, so the spreadsheets they bring should open there too. A Chrome XLSX Viewer sits right where files arrive, needs no license and starts at once. Nothing to update by hand and no separate window to look for: the XLSX File Viewer is just another tab. 🔹 How It Works 1. Install the extension and pin its icon 2. Click the icon to open the Web XLSX Viewer page 3. Drop a file, pick one, or paste a link 4. Browse sheets, search, copy what you need 🔹 Works on Any Desktop Wherever Chrome runs, the tool runs too, so it is an xlsx viewer for PC, Mac and Chromebook alike. It is a small xlsx viewer app next to your bookmarks, always one click away. On a computer without office software, the xlsx file viewer still does the job. 🔹 Who It Is For - Managers who open CSV file reports from the team every week - Students who need an XLSX Document Viewer for grade sheets and timetables - Freelancers reading a client's price list or invoice - Analysts who need a CSV Reader for quick exports - Anyone who wants to open xls file online without uploading it 🔹 What It Does Not Do It is a reader, not an editor. It does not change files, does not recalculate anything and does not convert between formats. You get a fast, read-only XLSX Reader, a .xlsx viewer for everyday reading.
