XLSX Editorby Loamstack
Start
Open an Excel workbook
View your sheets, edit cells, and save your workbook from one workspace.
Choose or drop an .xlsx file up to 50 MB. Workbook contents stay on this device.
- Explore your workbook
- Use Files and sheet tabs to move between worksheets. The ribbon and formula bar keep cell commands close to your data.
- Edit and save
- Make supported cell edits, then use Save to update your workbook or Save as to create a separate copy.
- Formula results
- Existing formulas display their stored results. Formulas are not recalculated when cells change.
Keep your original workbook
Selected files stay on your device. The source editor retains the original XLSX package and supported changes. Data exports use stored cell results and do not preserve workbook formulas or formatting; editing and calculation remain separate actions.
Use Edit source to keep working with the same workbook. Complex formulas and unsupported source features report their limits. Encrypted workbooks are not supported.
