Running Jupyterlab on Linux. Notebook reads and completes with no error but does not produce the excel file. Xlsxwriter code as follows:
file = "my_file.xlsx"
writer = pd.ExcelWriter(file, engine='xlsxwriter')
df.to_excel(writer, sheet_name='products')
wb = writer.book
ws = writer.sheets['products']
...etc
writer.save()
writer.close()
It runs ...no errors, but nothing is created. A full home directory search turns up nothing.
