Copy formula from one cell to another using openpyxl

Question

I would like to copy-paste the formula from one cell to another using openpyxl with the transposition you usually get when you use Excel.

For example, copying the formula =SUM(J3:J18) to the next column would automatically change it to =SUM(K3:K18) .

I found this method that could work by using win32com.client but I don't know any equivalent for openpyxl .

Is there a way to do this using openpyxl or shall I manually replace all the column numbers using regex?

Thanks

Answer 1

您将不得不手动执行此操作，但是您可能希望使用令牌处理程序，而不是编写自己的解析器。

openpyxl provides (at least now) some tools to translate formulae via the Translator class. It is mentionned in the page related to formulae tokenizer :

Here is an example on how to use it.

 >>> from openpyxl.formula.translate import Translator
 >>> ws['F2'] = "=SUM(B2:E2)"
 >>> # move the formula one colum to the right
 >>> ws['G2'] = Translator("=SUM(B2:E2)", "F2").translate_formula("G2")
 >>> ws['G2'].value
 '=SUM(C2:F2)'

Here is the current prototype of the function for translating formula:

def translate_formula(self, dest=None, row=None, col=None):
    """
    Convert the formula into A1 notation, or as row and column coordinates

    The formula is converted into A1 assuming it is assigned to the cell
    whose address is `dest` (no worksheet name).

    """
