使用Python 2解析超过255个字符的Excel工作表

Question

I have an Excel spreadsheet with 3 rows that I am parsing using Python2, and exporting the data to a .txt file. The third row is much more than 255 characters, so when the parser hits the end of the 255 column length, it cuts out the rest of the data. Is there anyway to deal with this?

from openpyxl import load_workbook
outf = open('c:\\Python27\\scripts\\saba_parser\\index.txt', 'w')
outf2 = open('c:\\Python27\\scripts\\IMS\\cse_errors.txt', 'w')
wb = load_workbook('c:\\Python27\\scripts\\saba_parser\\Copy of Saba_Views_good.xlsx')
s1 = wb.worksheets[0]


for r in s1:
   name = str(r[0].value)
   if r[2].value == None:
      tail = "None"
   else:
      #info = r[2].value.split("FROM")[-1]
      info = str(r[2].value)
      head, sep, tail = info.partition("FROM")
outf.write(name+','+tail+"\n")
#outf.write(name+','+info+"\n")

Any help would be appreciated.

Maybe if you load the workbook as "read only" , you could handle the long columns.

Apparently, if the file does not have the dimension properly set, this could lead to trouble

Read-only mode relies applications and libraries that created the file providing correct information about the worksheets, specifically the used part of it, known as the dimensions. Some applications set this incorrectly. You can check the apparent dimensions of a worksheet using ws.calculate_dimensions(). If this returns a range that you know is incorrect, say A1:A1 then simply resetting the max_row and max_column attributes should allow you to work with the file

Try using this patch to your code

wb = load_workbook('c:\\Python27\\scripts\\saba_parser\\Copy of Saba_Views_good.xlsx',read_only=True)
s1 = wb.worksheets[0]
# Only use the next line if s1.calculate_dimensions() does not give you the expected result
# s1.max_row = s2.max_column = None
