Answer 1

For me this worked well:

from win32com.client import Dispatch

app = Dispatch("Excel.Application")
workbook_file_name = 'Programmes.xlsx'
workbook = app.Workbooks.Open(Filename=workbook_file_name)

# WARNING: The following line will cause the script to discard any unsaved changes in your workbook
app.DisplayAlerts = False

i = 1
for sheet in workbook.Worksheets:
    for chartObject in sheet.ChartObjects():
        # print(sheet.Name + ':' + chartObject.Name)
        chartObject.Chart.Export("chart" + str(i) + ".png")
        i += 1

workbook.Close(SaveChanges=False, Filename=workbook_file_name)

Or this:

from win32com.client import Dispatch

app = Dispatch("Excel.Application")
workbook_file_name = 'Programmes.xlsx'
workbook = app.Workbooks.Open(Filename=workbook_file_name)
app.DisplayAlerts = False
try:
    workbook.SaveAs(Filename="ExcelCharts.htm", FileFormat=44)  # 44 = html file format
except Exception as ex:
    print(ex)
finally:
    workbook.Close(SaveChanges=False, Filename=workbook_file_name)
