Easily write formatted Excel from Python: Start with Excel formatted, use it in Python, and regenerate Excel from Python

问题:

I have to create Excel spreadsheet with nice format from Python. I thought of doing it by:

1. I start in Excel as it is very easy to format: I write in Excel the model I want, with the good format
2. I read this from Python
3. I create from Python an Excel spreadsheet with the same format

In the end, the purpose is to create from Python Excel spreadsheets, but formatting with xlwt takes a lot of time, so I thought of formatting first in Excel to help.

I have researched for easy ways to doing this but haven't found any. I can stick to my current working solution, using xlwt in Python to create formatted Excel, but it is quite awkward to use.

Thanks for any reply

Thanks for your replies. I've found what I was searching for at Preserving styles using python's xlrd,xlwt, and xlutils.copy. The code is below.

import xlrd  import xlutils.copy   inBook = xlrd.open_workbook('input.xls', formatting_info=True)  outBook = xlutils.copy.copy(inBook)   def _getOutCell(outSheet, colIndex, rowIndex):      """ HACK: Extract the internal xlwt cell representation. """      row = outSheet._Worksheet__rows.get(rowIndex)      if not row: return None      cell = row._Row__cells.get(colIndex)      return cell   def setOutCell(outSheet, col, row, value):      """ Change cell value without changing formatting. """      # HACK to retain cell style.      previousCell = _getOutCell(outSheet, col, row)      # END HACK, PART I      outSheet.write(row, col, value)      # HACK, PART II      if previousCell:          newCell = _getOutCell(outSheet, col, row)      if newCell:          newCell.xf_idx = previousCell.xf_idx      # END HACK    outSheet = outBook.get_sheet(0)  setOutCell(outSheet, 5, 5, 'Test')  outBook.save('output.xls')

You said:

and

it is quite awkward to use

Perhaps you are not using easyxf? If so, check out the tutorial that you can access via www.python-excel.org, and have a look at examples/xlwt_easyxf_simple_demo.py in your xlwt installation.
