xlsxwriter error: AttributeError: 'Workbook' object has no attribute 'add_format'

问题

I'm doing some simple conditional formatting using xlsxwriter but I am getting this error when I run the code below.

AttributeError: 'Workbook' object has no attribute 'add_format'

I have updated xlsxwriter and looked at a lot of questions on SO and documentation but nothing has worked yet.

This is my code:

workbook = load_workbook(input_excel_filename)
writer = pd.ExcelWriter(input_excel_filename, engine="xlsxwriter")
writer.sheets = dict((ws.title, ws) for ws in book.worksheets)

trends_sheet = writer.sheets["Trends"]
slight_increase = writer.book.add_format({"bg_color":"#d3e6d5"})
trends_sheet.conditional_format("E:E", {"type":"cell", "criteria":"==", "value":"Slight Increase", "format":slight_increase})

Part of the problem was I needed to set writer.book explicitly. So add the line writer.book = workbook after defining writer. Also adding engine="openpyxl" to the ExcelWriter got rid of a subsequent error. Altogether this seems to work:

workbook = load_workbook(input_excel_filename)
writer = pd.ExcelWriter(input_excel_filename, engine="openpyxl")
writer.book = workbook
writer.sheets = dict((ws.title, ws) for ws in wb.worksheets)
data.to_excel(writer, sheet_name="Data", index=False)
writer.save()
writer.close()

I couldn't get it to work with conditional formatting but setting formatting in the Excel spreadsheet directly actually seems to work, because even if the data is rewritten the formatting stays intact.

Check if xlsxwriter package is installed or not....even I faced the same issue..resolved it after installing the package...same answer goes for any attribute error issue related to workbook/writer if your code is correct
