工作表中命名范围的字典

Question

I have an Excel spreadsheet with a large number of named ranges in it. I would like to be able to get data from them in an efficient manner. Preferably in a python dictionary with the name of the range as the key and the value as the value. Or someway to make a pseudo workbook that lets me read a sheet without all the calls to excel.

Right now I am getting the value from each named range individually. This works, but is very slow. Ideally there would be one or two calls to get all of the named ranges. I am currently using a @xw.sub to get the values.

@xw.sub
def get_named_ranges():
    wb = xw.Book.caller()
    ranges = {}
    ranges['MyNamedRange1'] = wb.sheets['sheet1'].['MyNamedRange1'].value
    ranges['MyNamedRange2'] = wb.sheets['sheet1'].['MyNamedRange2'].value
    ranges['MyNamedRange3'] = wb.sheets['sheet1'].['MyNamedRange3'].value

You can perhaps use Pandas for this.

from pandas import *
xls = ExcelFile('test.xlsx')
df = xls.parse(xls.sheet_names[0])
print(df.to_dict())
