from asposecells.api import Workbook

# image path
image_name = 'screenshot.png'
image_path = fr'C:\\Users\\Bouregag Youcef\\Downloads\\Telegram Desktop\\analyses\\{image_name}'

# Export the dataframe to an Excel file
excel_name = 'table2.xlsx'
excel_path = fr'C:\\Users\\Bouregag Youcef\\Downloads\\Telegram Desktop\\analyses\\{excel_name}' 


workbook = Workbook(image_path)
workbook.save(excel_path)

I searched and found some suggestions, among them is to add java_home to environment variable and I do not and have not used it at all JAVA

Answer 1

I solved the problem by downloading and installing jdk and finally adding it to environment variable with name "JAVA_HOME"
