Pythonic reader and writer for DBF/XBase files

Project description


YDbf - reading and writing DBF/XBase files in a pythonic way. The library written in pure Python and have no external dependencies.

YDbf is compatible with Python 2.7+ and 3.5+.

What YDbf is good for:

  • export data to a DBF file
  • import data from a DBF file
  • read data from a DBF file as a stream

Where YDbf is not a good fit:

  • random access to records in a DBF file
  • memo fields

Read DBF

The entrypoint of YDbf is open function:

dbf ='simple.dbf')

You can use file name, or already opened in binary mode file:

fh = open('simple.dbf', 'rb')
dbf =

for record in dbf:

You may also use with statement:

with'simple.dbf') as dbf:
    for record in dbf:

Each record is a dict, which keys are names of fields.

Write DBF

YDbf opens file for reading by default, but you may set option mode to open for writing:

dbf ='simple.dbf', 'w', fields)

or open file yourself:

fh = open('simple.dbf', 'wb')
dbf =, 'w', fields)

fields is a structure description of DBF file, it is a required option for write mode. The structure is as sequence of field descriptions, where each fields described by tuple (NAME, TYPE, SIZE, DECIMAL). NAME is a name of field, TYPE -- DBF type of field ('N' for number, 'C' for char, 'D' for date, 'L' for logical), DECIMAL is a precision (useful for 'N' type only). For example:

fields = [
    ('ID',      'N',  4, 0),
    ('VALUE',   'C', 40, 0),
    ('UPDATE',  'D', 8, 0),
    ('VISIBLE', 'L', 1, 0),

YDbf uses unicode for 'C' fields by default, so you may want to define encoding which be used forthe DBF file. UTF-8 is not supported, you may use only 8-bit encodings.

dbf ='simple.dbf', 'w', fields, encoding='cp1251')

YDbf gets data as an iterator where each item is a dict, which keys are names of fields. For example,

data = [
    {'ID': 1, 'VALUE': 'ydbf', 'VISIBLE': True,
     'UPDATE':, 7, 14)},
    {'ID': 2, 'VALUE': 'ydbf-dev', 'VISIBLE': False,
     'UPDATE':, 5, 15)},
    {'ID': 3, 'VALUE': 'pytils', 'VISIBLE': True,
     'UPDATE':, 5, 11)},
