How to create row wise CSV for vectorized dataframe?

What I am trying to do is basically pulling out keywords from a processed file of a log file and creating a vectorized dataframe of those keywords. But when I am writing that dataframe into CSV, words are in the columns and their respective value in the second row. While I want the words to be in rows and their value in second column.

trial.py :

import re
import pandas as pd
from sklearn.feature_extraction.text import CountVectorizer
from sklearn.feature_extraction.text import ENGLISH_STOP_WORDS

def removeNumbers(list):
   #doing something

def processFiles(filename):
   #doing something

def readFile(fileName):
   #doing something

# Build our text
processFiles("log.txt")
text = readFile("processedFile.txt")


vectorizer = CountVectorizer()

matrix = vectorizer.fit_transform([text])

counts = pd.DataFrame(matrix.toarray(),
                      columns=vectorizer.get_feature_names_out())



counts.to_csv("keywords_count.csv")

keywords_count.csv looks like this :
