@yashpatel12 I see these options:
- export data to a new Excel sheet which you use then
- export to a CSV file and import in Excel or connect via [Power Query]
(About Power Query in Excel - Microsoft Support) - export to a local database and connect via ODBC
- use the Excel Cell Updater to write data to Excel
- use OpenPyxl (now bundled with KNIME/Python) to add data to Excel or manipulate cells or sheets (use Python Pandas and Openpyxl to import and export Excel (sheets) and Export them back - also append to an existing Excel file – KNIME Community Hub)
