Python Error : “_csv.Error: field larger than field limit ” – Resolved

The error message indicates that while reading the CSV file, the program encountered a field that was larger than the default field size limit, which is 131072 characters. This is a safety mechanism in Python’s csv module to prevent consuming excessive memory when reading malicious or malformed CSV files.

You can remedy this situation by increasing the field size limit using the csv.field_size_limit function before reading the file.

Here’s how you can modify your code:

import csv
import sys

# Increase the field size limit
csv.field_size_limit(sys.maxsize)

with open('filename.csv', 'r') as file:
    reader = csv.reader(file)
    
    # Iterate over each row in the CSV
    for row in reader:
        print(row)
