Script

The following script works well for most DBF files. But gives the error above for some files. I did not understand why, but perhaps it is an issue with this repo?

#!/usr/bin/python

import csv
from dbfpy3 import dbf
import os
import sys

def execute(filename):
	if filename.lower().endswith('.dbf'):
		print("Converting %s to csv" % filename)
		csv_fn = filename[:-4]+ ".csv"
		with open(csv_fn,'w',  newline='') as csvfile:
			in_db = dbf.Dbf(filename)
			out_csv = csv.writer(csvfile)
			names = []
			for field in in_db.header.fields:
				names.append(field.name)        
			out_csv.writerow(names)
			for rec in in_db:
				out_csv.writerow(rec.fieldData)
			in_db.close()
			print("Done...")
	else:
	  print("Filename does not end with .dbf")


folder = sys.argv[1]
if os.path.isfile(folder):
	execute(folder);
else:
	for name in os.listdir(folder):
		filename = os.path.join(folder, name)
		execute(filename)

The issue was fixed after adding the following line at line 307 in fileds.py

value = value.decode('utf-8')
