BDP formula not working with write_formula

Hi,

I am using XlsxWriter to do write a BDP formula to a cell in Excel but it appears to do causes errors and outputs 0.0, as well as presenting a series of errors when opening the outputted excel file.

import xlsxwriter

orders_file =  r'Q:\.....'
date_extension = str(date) + '.xlsx'
writer = pd.ExcelWriter(orders_file+date_extension, engine = 'xlsxwriter')
df.to_excel(writer, sheet_name='Loans', index=False,startrow=1,startcol = 3, header=True)
loans_sheet = writer.sheets['Loans']    
worksheet.write_formula('B3', "=BDP(LEFT(C3,LEN(C3)-1)&' Corp', 'Issuer')")

workbook.close()

I’ve deleted all other information, and the Loans tab has the necessary info written to it before I try to put the formula there. Deleting the other info and saving it again seems to get rid of these errors but the value is still 0.0 This is the log file of errors that comes up :

I downloaded what I just uploaded and I do see a formula and an output from the BBG formula.

Apologies. I mistook the first and second files.

You can try the following. It loads but doesn’t calculate anything for me, since I don’t have the Bloomberg plugin. Note the _xll. prefix and that it should probably be an array formula. Also, the formula should have double quotes not single quotes:

from xlsxwriter.workbook import Workbook
    
workbook = Workbook('test.xlsx')
worksheet = workbook.add_worksheet()

worksheet.write_array_formula('B4', '_xll.BDP(LEFT(C3,LEN(C3)-1)&" Corp", "Issuer")')

workbook.close()

Good stuff. Thanks for sending the file. I’ll up date the StackOverflow question.
