Python script to convert DBF database file to CSV

• First download dbfpy: http://sourceforge.net/projects/dbfpy/files/latest/download?source=files
• Then install: sudo python setup.py install

To convert DBF file to CSV:

./dbf2csv database.dbf

dbf2csv.py

#!/usr/bin/python

import csv
from dbfpy import dbf
import os
import sys

filename = sys.argv[1]
if filename.endswith('.dbf'):
    print "Converting %s to csv" % filename
    csv_fn = filename[:-4]+ ".csv"
    with open(csv_fn,'wb') 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"

Thanks mate, that's really handy.

Just that I need. Spasibo, tovarish.

cool, thanks

This is great.. thank you very much!! Gracias!

Of course you wrote this, @bertspaan!

Good afternoon, thanks for your code, but i have a doubt,
I have a dbf file of 2gb, your program export this a csv file very good, but i need that this csv has comlums wth character delimiter ";"...

Thank you for the script. Unfortunately, it handles ÄÖÜ and stuff not correct, must be a codepage problem. I guess its in dbfpy.

@bertspaan thank you very much!

@mruepp I think the problem is in the encoding. Try to convert your dbf to csv and then specify the encoding when opening the csv file.

Adapting a Python 3 https://gist.github.com/celisflen-bers/fe827aa724997b0487a084d225054e2c

If you want to change the delimiter try this at line 14

out_csv = csv.writer(csvfile,delimiter='|')
where "|" would be the delimiter... you can choose ";" "@" ,etc

Thanks. Simple and effective

Thanks mate! It was very helpful!

I apply this for one file and I got

Traceback (most recent call last):
  File "dbf2csv.py", line 19, in <module>
    for rec in in_db:
  File "/usr/local/lib/python2.7/dist-packages/dbfpy/dbf.py", line 262, in __getitem__
    return self.RecordClass.fromStream(self, self._fixIndex(index))

    return int(value)

how to install dbfpy module in virtual env.?

Thanks!

@rpsingh21 just pip install dbfpy

Don't work with my DBF file.

Tried this :

import sys
from dbfpy import dbf

db = dbf.Dbf("/home/thomas/repert1709.dbf")
print db
print

And got :

Traceback (most recent call last):
  File "./converter.py", line 7, in <module>
    db = dbf.Dbf("/home/thomas/repert1709.dbf")
  File "/home/thomas/.local/lib/python2.7/site-packages/dbfpy/dbf.py", line 138, in __init__
    self.header = self.HeaderClass.fromStream(self.stream)
  File "/home/thomas/.local/lib/python2.7/site-packages/dbfpy/header.py", line 128, in fromStream
    _fld = fields.lookupFor(_data[11]).fromString(_data, _pos)
  File "/home/thomas/.local/lib/python2.7/site-packages/dbfpy/fields.py", line 473, in lookupFor
    return _fieldsRegistry[typeCode]
KeyError: 'B'

If you need to filter columns you can use this script
Try this:

#!/usr/bin/python

import csv
from dbfpy import dbf
import os
import sys
import json
from argparse import ArgumentParser

description = 'Arguments of DBF to CSV converter'
parser = ArgumentParser(description=description)
parser.add_argument('-f', '--file', dest='file', required='true',
                    help="Examples: -i file.dbf")

parser.add_argument('-c', '--colunms', dest='colunms',
                    type=str, nargs='*',
                    help="Examples: -c item1 item2 item3")

opts = parser.parse_args()

if opts.file.endswith('.dbf') or opts.file.endswith('.DBF'):
    print "Converting %s to csv" % opts.file
    csv_fn = opts.file[:-4]+ ".csv"
    with open(csv_fn,'wb') as csvfile:
        in_db = dbf.Dbf(opts.file)
        out_csv = csv.writer(csvfile)
        names = []
        colunmsKeySave = {}
        for keyF, field in enumerate(in_db.header.fields):            
            if opts.colunms:
                for ig in opts.colunms:
                    if ig == field.name:
                        names.append(field.name)
                        colunmsKeySave[keyF] = field.name
            else:
                names.append(field.name)
        out_csv.writerow(names)

        for rec in in_db:
            if opts.colunms:
                values = []
                for keyf, field in enumerate(rec.fieldData):
                    if keyf in colunmsKeySave:
                        values.append(field)
                out_csv.writerow(values)
            else:
                out_csv.writerow(rec.fieldData)

        in_db.close()
        print "Done..."
else:
  print "Filename does not end with .dbf"

This library worked for me: https://github.com/akadan47/dbf2csv
For Python 3: akadan47/dbf2csv#1

It uses the underlying dbfread library (https://github.com/olemb/dbfread) instead of dbfpy (http://dbfpy.sourceforge.net/)

If you need to filter columns you can use this script
Try this:

Plese tell what to write in the line of

description = 'Arguments of DBF to CSV converter'
parser = ArgumentParser(description=description)
parser.add_argument('-f', '--file', dest='file', required='true',
help="Examples: -i file.dbf")

parser.add_argument('-c', '--colunms', dest='colunms',
type=str, nargs='*',
help="Examples: -c item1 item2 item3")

I have DBF file with 9500 lines and and A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,,R,S,T,U,W,X,Y,Z,AA,AB.... AQ columnes.

And i have to convert the last 130 lines with all columnes
Any idea.
Thank you

when I tried this code:

from dbfpy import dbf
path = "a/path/to/dbf/file/"
in_db = dbf.Dbf(path)

immediately I got this error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/dbfpy/dbf.py", line 128, in __init__
    self.stream = file(f, ("r+b", "rb")[bool(readOnly)])
IOError: [Errno 13] Permission denied: 'a/path/to/dbf/file.DBF'

Somehow it works with some of my .DBF files, but not all... Is there something wrong with my files? or limitation with dbf.Dbf() function?

I am running this on Python 3 and it throws the error on dbf. NameError: name 'Dbf' is not defined.
Any suggestions on how to proceed with this?

Nice dude ;)

Scan the directory for all DBF files. File extension case-insensitive. And commented code that writes the header

#!/usr/bin/python

import csv
from dbfpy import dbf
import os
import sys

csv_fn = "all.csv"
with open(csv_fn,'wb') as csvfile:
  for file_name in os.listdir('.'):
    if file_name.lower().endswith('.dbf'):
      print ("Converting %s to csv" % file_name)
      in_db = dbf.Dbf(file_name)
      out_csv = csv.writer(csvfile)

      #names = [] # no header
      #for field in in_db.header.fields:
      #names.append(field.name)

      for rec in in_db:
          out_csv.writerow(rec.fieldData)
      in_db.close()
      print ("Done...")
    else:
      print ("Filename does not end with .dbf")

my dbf contain UTF8 and/or chinese words. currently the data became monster words ( e.g. ∂◊¬◊´H¶´ ). how can i fix it ?
