I've been using pandas for a while and I think it is a great tool. I made a program to generate some excel files from some data collected by the user. The final user have been testing and using it for 6 months; it never failled till yesterday, when it generated a dagamaged excel file. When I opened it with a text editor, it was totally blank. The code to generate this file is this:
escritor = pandas.ExcelWriter(direccion, engine='xlsxwriter')
listaTotal.to_excel(escritor, index = False)
escritor.save()
and:
escritor = pandas.ExcelWriter(direccion + '.xlsx', engine='xlsxwriter')
self.listaFact.to_excel(escritor, index = False, startrow = 1, startcol = 0, sheet_name = 'Hoja1')
escritor.save()
The second code fragment also uses some format options for the 'xlsxwriter', an example here:
format = workbook.add_format()
format.set_font_size(9)
format.set_font_name('Sans Serif 12cpi')
format.set_border()
format.set_text_wrap()
This error happened twice; about 1 month ago and yesterday. I can't duplicate the error, I don't know what happened. And also the traceback is here, it shows the problem when the program reads the file, but this file was generated by the code posted before:

I am building automation for Excel a multi-tabbed excel document. When I try to close the document I get the error below (full traceback, minus the personal details at the top), which then is corrupted and I cannot open the xlsx document. Unfortunately I haven't found any clues to go off of. I am using xlsxwriter functions to set row and column formatting, from what I've found this could be an issue but I haven't been able to track it down. Any thoughts on possible solutions?

I have a folder with many xlsx files that I'd like to convert to csv files.
During my research, if found several threads about this topic, such as this or that one. Based on this, I formulated the following code using glob and pandas:
import glob
import pandas as pd
path = r'/Users/.../xlsx files'
excel_files = glob.glob(path + '/*.xlsx')
for excel in excel_files:
out = excel.split('.')[0]+'.csv'
df = pd.read_excel(excel) # error occurs here
df.to_csv(out)
But unfortunately, I got the following error message that I could not interpret in this context and I could not figure out how to solve this problem:

Does anyone know how to fix this? Thanks a lot for your help!
I had the same problem here. After some hours thinking and searching I realized the problem is, actually, the file. I opened it using MS Excel, and save. Alakazan, problem solved.
The file was downloaded, so i think it's a "security" error or just an error from how the file was created. xD
EDIT:
It's not a security problem, but actually an error from the generation of file. The correct has the double of kb the wrong file.
An solution is: if using xlrd==1.2.0 the file can be opened, you can, after doing this, call read_excel to the Book(file opened by xlrd).
import xlrd
# df = pd.read_excel('TabelaPrecos.xlsx')
# The line above is the same result
a = xlrd.open_workbook('TabelaPrecos.xlsx')
b = pd.read_excel(a)
I try to read a xlsx into a data frame:
itut_ir = pd.read_excel('C:\\Users\\Administrator\\Downloads\\reportdata.xlsx')
print(itut_ir.to_string())
I receive this:

does anybody have an idea? the file does not seem to be broken, I can open it with Excel.
thanks!
*** UPDATE ***
the file producing the error is being downloaded from FTP. opening the original file works ... if that gives you a hint :) thanks
I had the same issue just a little bit ago with an XLSX that I created in LibreOffice.
The solution was to check the XLSX to make sure it wasn't corrupted. In my case, loading a previous version of the XLSX file corrected the problem.
I am working on a personal project to analyze COVID19 data. Presently, I am download the excel sheet provided by ourworldindata.org, available at this url -> https://github.com/owid/covid-19-data/blob/master/public/data/owid-covid-data.xlsx
However, when i try to execute the command in pandas (below), I get a list of errors. What could be the root cause ?
url = 'https://github.com/owid/covid-19-data/blob/master/public/data/owid-covid-data.xlsx'
df = pd.read_excel(url, sheet_name='Sheet1')

Please not that pandas can read the excel if I download it on my computer
Try the link to raw excel file:
import pandas as pd
url='https://github.com/owid/covid-19-data/blob/master/public/data/owid-covid-data.xlsx?raw=true'
df=pd.read_excel(url, sheet_name='Sheet1')
You can do it with requests
import pandas as pd
import io
import requests
url = 'https://github.com/owid/covid-19-data/blob/master/public/data/owid-covid-data.xlsx'
get_content = requests.get(url).content
df = pd.read_csv(io.StringIO(get_content .decode('utf-8')))
I do this to avoid using local drive or google drive , and saves time of connection.
I'm quit new to coding in general.
What i want to achieve is to make an script that runs to a list of employers in excel and weekly generate a new hour-sheet. And by generating i mean copy for every employer an empty hour-sheet and rename it, and also change the week-number and employer-name in the newly made copy.
I didn't start with a loop, because i first wanted to made the part that change the employers-name and week-number. I've already search the internet for some answers, but i can't get the code to work, keep getting error messages.
So here is my code so far:
import os
import shutil
import time
from openpyxl import load_workbook
#calculate the year and week number
from time import strftime
year = (time.strftime("%Y"))
week = str(int(time.strftime("%W"))+1)
year_week = year + "_" + week
#create weekly houresheets per employer
employer = "Adam"
hsheets_dir = "C:\\test\\"
old_file_name = "blanco.xlsx"
new_file_name = employer + "_" + year_week + ".xlsx"
dest_filename = (hsheets_dir + new_file_name)
shutil.copy2((hsheets_dir + old_file_name), dest_filename)
#change employer name and weeknumber
def insert_xlsx(dest, empl, wk):
#Open an xlsx for reading
print (dest)
wb = load_workbook(filename = dest)
#Get the current Active Sheet
ws = wb.get_sheet_by_name("Auto")
ws.cell(row=1,column=2).value = empl
ws.cell(row=2,column=2).value = wk
wb.save(dest)
insert_xlsx(dest_filename, employer, week_str)
And here is the error message i keep getting:
Traceback (most recent call last):

Can somewone put me in the right directions?
Many thanks
I think based on your responses then that the problem lies with your existing hour-sheet Excel spreadsheet:
Try starting with a copy of your existing spreadsheet and removing all of the entries. Hopefully this too will work.
If this fails, start with a new blank spreadsheet.
Bit by bit copy the existing data and repeat your script.
By doing this you will might be able to isolate the feature which is not compatible with openpyxl.
Alternatively, you might be able to write the whole thing from your Python script, and skip trying to modify a semi-filled in one. This would then be 100% compatible.
