HI @Shas_DataE, Good Day!
Could you please check and confirm if there are any special characters in the table column? At this moment, special characters are compatible with Excel.
If yes then please drop the column that has that special character and then you can export the results to Excel.
Also please note that there is a known issue where exporting SQL query results via the UI has a limit of 100k rows to Excel, and more to CSV/TSV.
Please let me know if this helps and leave a like if this information is useful, followups are appreciated.
Kudos
Ayushi
