My code:
import csv
# Create a list of Gujarati strings
strings = [['હેલો, વર્લ્ડ!', 'સુપ્રભાત', 'મારા નામ હેઠળ છે']]
# Open the CSV file in 'w' mode
with open('Gujarati.csv', 'w', encoding='utf-16',newline='') as f:
# Create a CSV writer
writer = csv.writer(f)
# Write the strings to the CSV file
writer.writerows(strings)
I am trying to write each heading as a different column, but I don't know why it is getting in the same column. I want it to be in separate columns. I don't know what else to write but feel free to ask me anything anytime.
I appreciate any help you can provide

Import or export text (.txt or .csv) files You can change the separator character used in both delimited and .csv text files. This may be necessary to ensure that the import or export operation works the way you want it to.
I want to write strings that include semicolons to CSV.
This is what I have:
name = ["Peter;Parker"]
file = open("Test.csv", "a", newline='')
writer = csv.writer(file, delimiter=',')
writer.writerow(name)
So the problem is, I want the complete string name in column 1, but in fact the semicolon splits the part before and after into column 1 and column 2
So the comment from #snakecharmerb was correct.
In my case I was trying to open the csv file with Excel and Excel has Semicolon as a default delimiter.
Instead of double clicking the csv file to open Excel you can check if the raw text is correct by editing the file via notepad.
If you want to open it with Excel you need to load an empty excel file and go to Data and import from Text. Now load the csv file and you are asked which delimiter you want to use, no you can unselect semicolon and choose none or just ,
I'm using Python, and with the library gdata I can upload a .csv file, but the delimiter stays as default, that is comma (","). How can I do to change the delimiter to, for example, ";" ?
What I want is, from Python, change the delimiter of an uploading file. I don't want to change the "," to ";", I want to change the delimiter.
You could open the .csv using excel, then it knows its a csv (Comma Delimeted file) but you can set other things to 'delimit' the file by such as spaces etc.
Edit: Sorry, should've mentioned, don't open the file using the 'open with' method, open Excel first, then open the file from within Excel. This should open the 'Text Import Wizard' - Where you can choose what to delimt the file with such as tab,semicolon,comma,space etc.
I am assuming you really need to select this delimiter through gdata, right?
Otherwise you can easily change the delimiter in a shell with something like:
cat my_csv.csv | tr ',' ';' > my_csv_other_delimiter.csv
You can also easily replace these symbols in your python code. It could be an overload if you receive your csv files from somewhere else and you cannot control the symbol you use as a delimiter, but if there is no choice that could be an option.
I have many Python scripts that output CSV files. It is occasionally convenient to open these files in Excel. After installing OS X Mavericks, Excel no longer opens these files properly: Excel doesn't parse the files and it duplicates the rows of the file until it runs out of memory. Specifically, when Excel attempts to open the file, a prompt appears that reads: "File not loaded completely."
Example of code I'm using to generate the CSV files:
import csv
with open('csv_test.csv', 'wb') as f:
writer = csv.writer(f)
writer.writerow([1,2,3])
writer.writerow([4,5,6])
Even the simple file generated by the above code fails to load in Excel. However, if I open the CSV file in a text editor and copy/paste the text into Excel, parse it with text to columns, and then save as CSV from Excel, then I can reopen the CSV file in Excel without issue. Do I need to pass an additional parameter in my scripts to make Excel parse the CSV files the same way it used to? Or is there some setting I can change in OS X Mavericks or Excel? Thanks.
Maybe I had the similar problem, the error message "SYLK: File format is not valid" when open python autogenerated csv file. The solution is really funny. The first two characters must not be I and D in uppercase (ID). Also see "SYLK: File format is not valid" error message when you open file.
Possible solution1: use *.txt instead of *.csv. In this case Excel (at least, 2010) will show you an import data wizard where you can specify delimiters, character encoding, field types, etc.
UPD: Solution2:
The python "csv" module has a "dialect" feature. For example, the following modification of your code generates valid csv file for my environment (Python 2.7, Excel 2010, Windows7, locale with ";" list delimiters):
import csv
with open('csv_test2.csv', 'wb') as f:
csv.excel.delimiter=';'
writer = csv.writer(f, dialect=csv.excel)
writer.writerow([1,2,3])
writer.writerow([4,5,6])
I have a csv file which contains rows from a sqlite3 database. I wrote the rows to the csv file using python.
When I open the csv file with Ms Excel, a blank row appears below every row, but the file on notepad is fine(without any blanks).
Does anyone know why this is happenning and how I can fix it?
Edit: I used the strip() function for all the attributes before writing a row.
Thanks.
You're using open('file.csv', 'w')--try open('file.csv', 'wb').
The Python csv module requires output files be opened in binary mode.
the first that comes into my mind (just an idea) is that you might have used "\r\n" as row delimiter (which is shown as one linebrak in notepad) but excel expects to get only "\n" or only "\r" and so it interprets this as two line-breaks.
