Openpyxl 可以从 excel 中读取数组公式吗？

Question

I am creating a tool that reads excel formula in order to do some analysis on the functions used. I am currently using openpyxl to read in the formulae of an excel workbook, but I am encountering an issue where array formula are read in as an equals sign only, ie, = .

The code I am using to read the formulae is:

wb = openpyxl.load_workbook(book, data_only=False)

An array formula is of the form {=SUM(LEN(B2:B11))} or ={formula}

It seems to be the curly braces { which cause the issue. Has anyone experienced this issue before, or know of a workaround (using a different library if necessary) for this issue?

Cheers,

Matthew

Answer 1

Array formulae are currently (openpyxl 3.0.x) stored separately in the ws.formula_attributes dictionary.

The curly brackets for array formulae and data tables (coming) are GUI-only artefacts.
