Hi Mormukut Chaudhary
Thanks for reaching out! Currently, Mode only supports uploading CSV files to our Public Data Warehouse: https://help.modeanalytics.com/articles/upload-public-data-to-mode/
As another option, if the CSV file is hosted somewhere that can be retrieved via a URL, you should be able to import your file since we do support the Requests library for Python.
For more information on this, please see the following example report on how to your import data via URL: https://modeanalytics.com/modeanalytics/reports/495f4647b639 You can view the Python code by clicking View Details -> Notebook. Please note, the code is in the second cell.
Let me know if you have any further questions, thanks!
