Excel Workbook Viewer
Open XLSX or XLS files, switch worksheets, search values, and preview cells locally
Excel Workbook Viewer — what it does
Open an XLSX or XLS file directly in the browser, switch between its worksheets, search cell contents and see the row and column counts at a glance. It is a reading room for spreadsheets: nothing recalculates, nothing gets reformatted on open, and nothing you look at leaves the machine.
When this tool helps
- Inspecting a workbook on a computer that has no Excel installed.
- Checking what an emailed spreadsheet contains before opening it in your real environment.
- Finding which sheet and cell holds a value when all you have is a search term.
How to use it
- Choose the Excel file.
- Pick a worksheet from the selector.
- Use search to locate values across cells.
- Read the rows and columns counts for each sheet.
Accuracy, limits, and good practice
- Viewing avoids the classic Excel-on-open mutations — dates reinterpreted, leading zeros dropped — because nothing is written back.
- Search matches cell text, which is the displayed value; a number formatted as currency is found by its digits, not the symbol.
- Very wide sheets are easier to inspect after extracting the relevant columns with the Excel column extractor.
Frequently asked questions
Do formulas show their values?
The stored calculated values are shown, as saved by the application that last wrote the file.
Can I edit cells here?
No, this is deliberately read-only. Use the find and replace or filter tools to produce modified copies.
Does it open password-protected files?
Encrypted workbooks cannot be read. Remove the protection in Excel first if inspection is needed.

Excel 活頁簿檢視器能做什麼
直接在瀏覽器中開啟 XLSX 或 XLS，切換工作表、搜尋儲存格內容，並一眼看到列數與欄數。它是試算表的閱覽室：不重算、開啟時不重排格式，你看的一切也不會離開這台電腦。
什麼時候用得上
- 在沒裝 Excel 的電腦上檢視活頁簿。
- 在正式環境開啟之前，先確認郵件附件的試算表內容。
- 只有一個關鍵字時，找出值藏在哪個工作表、哪個儲存格。
使用步驟
- 選擇 Excel 檔案。
- 從選單挑選工作表。
- 用搜尋在儲存格間定位數值。
- 查看各工作表的列數與欄數。
精確度、限制與實務建議
- 純檢視可避開 Excel 開檔即改的老毛病——日期被重新解讀、前置零被吃掉——因為不會寫回任何內容。
- 搜尋比對的是儲存格顯示文字；格式化成貨幣的數字要用數字找，不是用符號找。
- 特別寬的工作表，先用 Excel 欄位提取工具抽出相關欄位再看會輕鬆得多。
常見問題
公式會顯示結果嗎？
顯示的是最後寫入檔案的應用程式所儲存的計算值。
可以在這裡編輯儲存格嗎？
不行，這是刻意唯讀的。要修改請用尋找取代或篩選等工具產生副本。
可以開啟有密碼的檔案嗎？
加密的活頁簿無法讀取。需檢視時請先在 Excel 中移除保護。
