Python win32com-将文本框中的文本读取到单元格吗？

Question

I would like to read the text from a text box in an Excel File and save that value to a variable. The problem I am having is with the reading of the TextBox. I have tried several methods, this one showed the most promise, as it does not generate an error, but it does not elicit the desired result either. Any suggestions are appreciated. See code below.

import win32com.client as win32 
excel = win32.gencache.EnsureDispatch('Excel.Application')
wb = excel.Workbooks.Open("C:\\users\\khillstr\\Testing\\Scripts\\Book1.xlsx")
excel.Visible = False

ws = wb.Worksheets

canvas = excel.ActiveSheet.Shapes

for shp in canvas.CanvasItems:
    if shp.TextFrame.Characters:
        print shp.TextFrame.Characters
    else:
        print "no"

Answer 1

Canvas has to do with graphics in excel files. I think you want access to the cells. Below is code that prints out each row as a tuple.

import win32com.client as win32 
excel = win32.gencache.EnsureDispatch('Excel.Application')
wb = excel.Workbooks.Open("C:\\users\\khillstr\\Testing\\Scripts\\Book1.xlsx")
excel.Visible = False

sheet = wb.Worksheets(1)

for row in sheet.UsedRange.Value:
  print row

Answer 2

import win32com.client as win32

file_name = 'path_to_excel'

excel = win32.gencache.EnsureDispatch('Excel.Application')
wb = excel.Workbooks.Open(self.file_name)
excel.Visible = False

sheet = wb.Worksheets(1)
deep = lambda r,c: sheet.Cells(r,c)
print(deep(row_num,col_num))

excel.Application.Quit()

This code will open an excel located at 'path_to_excel' and read a cell located at (Row_Number = row_num, Column_Number = col_num)

要在工作表上的文本框对象中获取文本，您需要使用shp.TextFrame.Characters.Caption因为Characters方法返回的是Characters对象而不是字符串。
