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.
