Snowflake python sheet store file at stage

I have the following small test, where I would like to store a xlsx file at internal stage in snowflake:

import snowflake.snowpark as snowpark
import xlsxwriter
import pandas as pd
from snowflake.snowpark.functions import col

def main(session: snowpark.Session): 
# Your code goes here, inside the "main" handler.
tableName = 'information_schema.packages'
dataframe = session.table(tableName).filter(col("language") == 'python')

x = dataframe.to_pandas()
unload_location = "@JV_TEST/jv.xlsx"

x.to_excel(unload_location)
# Print a sample of the dataframe to standard output.
dataframe.show()

# Return value will appear in the Results tab.
return dataframe

But I get the following error:

Traceback (most recent call last):
  Worksheet, line 17, in main
  File "pandas/util/_decorators.py", line 211, in wrapper
    return func(*args, **kwargs)

    super().__init__(

    self._handles = get_handle(

    check_parent_directory(str(handle))

    raise OSError(rf"Cannot save file into a non-existent directory: '{parent}'")
OSError: Cannot save file into a non-existent directory: '@JV_TEST'

How can I store the file at stage? (I would like to use pandas and xlsxwrite, because I would like to apply some stuff to the excel sheet)

At this time it is not possible to write to a stage using Python Worksheets.
The general limitations from Python Stored Procedures and UDFs apply also to Python Worksheets.

This means you can only write files to /tmp and once your session is terminated the files won't be accessible anymore from /tmp.
You can only write to /tmp using Python's built in functions like open(), it doesn't work with external ones like xlsxwriter.

As a general rule, manipulations of files stored on a stage using Python is not possible.
