Open a workbook and find what is inside
Need to check an Excel file without opening a full spreadsheet application? Load the workbook to review worksheets, search for a value, and inspect cells before you decide whether to edit or convert it.
1. Select the workbook
Browse for an Excel file or use the sample workbook. Keep the original available in case you need to compare a cell or sheet later.
2. Choose the worksheet
Use the sheet tabs to move between worksheets. A value may be on another sheet, so check the workbook tabs before concluding that data is missing.
3. Search and inspect cells
Search for an order number, name, or other value. If the workbook includes formulas, use the formula display option where available to distinguish a formula from its displayed result.
4. Decide on the next step
Use the viewer for inspection. If you need to change formulas, formatting, or workbook structure, make those changes in a spreadsheet editor and save a separate copy.
What a viewer may not preserve
A browser-based view is useful for checking cell contents, but it is not a replacement for every Excel feature. Complex formatting, macros, external links, pivot tables, and workbook-specific behaviour may require Excel or another compatible spreadsheet application. Do not assume that viewing a workbook confirms every formula or feature will behave identically elsewhere.
Frequently asked questions
Can I find a value across worksheets?
Use the available search and check each worksheet if the workbook's search scope is limited. Always confirm the sheet and surrounding cells for a match.
Does viewing change the workbook?
The viewer is intended for inspection. Keep the source file unchanged and use a spreadsheet editor when you need to modify and save workbook content.
