The two parameters are encoding ='UTF-8' and errors='ignore'. This allowed me to create a duplicate of original CSV without the headers and without the UnicodeDecodeError. Below is the completed code.

This article concerns the conversion and handling of CSV file formats in combination with the UTF-8 encoding standard. 💡 The Unicode Transformation Format 8-Bit
(UTF-8) is a variable-width character encoding used for electronic communication. UTF-8 can encode more than 1 million (more or less weird) characters using 1 to 4 byte code units. Example UTF-8 characters: ☈,☇,★,☃,☄,☍ UTF-8 is the default encoding standard on Windows, Linux, and macOS. If you write a CSV file using Python’s standard file handling operations such as open() and file.write(), Python will automatically create a UTF-8 file. So if you
came to this website searching for “CSV to UTF-8”, my guess is that you read a different encoded CSV file format such as ASCII, ANSI, or
UTF-16 with some “weird” characters. Say, you want to read this ANSI file: Now, you can simply convert this to an UTF-8 CSV file via the following approach:
CSV to UTF-8 Conversion in PythonThe no-library approach to convert a CSV file to a CSV
UTF-8 file is to open the first file in the non-UTF-8 format and write its contents back in an UTF-8 file right away. You can use the with open('my_file.csv', 'r', encoding='ANSI', errors='ignore') as infile: with open('my_file_utf8.csv', 'w') as outfile: outfile.write(infile.read()) After conversion from ANSI to UTF-8 using the given approach, the new CSV file is now UTF-8 formatted: CSV Reader/Writer – CSV to UTF-8 ConversionYou don’t need a CSV reader to convert a
CSV to UTF-8 as shown in the previous example. However, if you wish to do so, make sure to pass the import csv with open('my_file.csv', 'r', encoding='ANSI', errors='ignore') as infile: with open('my_file_utf8.csv', 'w', newline='') as outfile: reader = csv.reader(infile) writer = csv.writer(outfile) for row in reader: print(row) writer.writerow(row) The extra The output is the same UTF-8 encoded CSV:
Pandas – CSV to UTF-8 ConversionYou can use the Here’s an example: import pandas as pd df = pd.read_csv('my_file.csv', encoding='ANSI') df.to_csv('my_file_utf8.csv', encoding='utf-8', index=False) ANSI to UTF-8The no-library approach to convert an ANSI-encoded CSV file to a UTF-8-encoded CSV file is to open the first file in the ANSI format and write its contents back in an UTF-8 file. Use the Here’s an example: with open('my_file.csv', 'r', encoding='ANSI', errors='ignore') as infile: with open('my_file_utf8.csv', 'w') as outfile: outfile.write(infile.read()) This converts the following ANSI file to an UTF-8 file: Related Tu While working as a researcher in distributed systems, Dr. Christian Mayer found his love for teaching computer science students.

How do I fix encoding in Python?The best way to attack the problem, as with many things in Python, is to be explicit. That means that every string that your code handles needs to be clearly treated as either Unicode or a byte sequence. The most systematic way to accomplish this is to make your code into a Unicode-only clean room.
What is UTFUTF-8, or "Unicode Transformation Format, 8 Bit" is a marketing operations pro's best friend when it comes to data imports and exports. It refers to how a file's character data is encoded when moving files between systems.
