Excel 2007+ Binary Workbook (xlsb) parser
pyxlsb2 (a variant of pyxlsb - https://github.com/wwwiiilll/pyxlsb) is an Excel 2007+ Binary Workbook (xlsb) parser written in Python.
pyxslb2 offers the following improvements/changes in comparison to pyxlsb:
- By default, keeps all data in memory instead of creating temporary files. This is mainly to speed up the processing and also not changing the local filesystem during the processing.
- relies on both “xl\workbook.bin” and “xl\_rels\workbook.bin.rels” to load locate boundsheets. As a result, it can load all worksheets as well as all macrosheets.
- extracts macro formulas:
- accurately shows the formulas
- supports A1 addressing
- supports external addressing (partially implemented))
- extracts defined names such as auto_open
- Installing the whl file

Extract the zip file and go to the extracted directorypython setup.py install –user
The module exposes an open_workbook(name) method (similar to Xlrd and OpenPyXl) for opening XLSB files. The Workbook object representing the file is returned.
from pyxlsb2 import open_workbook with open_workbook('Book1.xlsb') as wb: # Do stuff with wb
The Workbook object exposes a get_sheet_by_index(idx) and get_sheet_by_name(name) method to retrieve Worksheet instances.
# Using the sheet index (0-based, unlike VBA) with wb.get_sheet_by_index(0) as sheet: # Do stuff with sheet # Using the sheet name with wb.get_sheet_by_name('Sheet1') as sheet: # Do stuff with sheet
A sheets property containing the sheet names is available on the Workbook instance.
The rows() method will hand out an iterator to read the worksheet rows. The Worksheet object is also directly iterable and is equivalent to calling rows().
# You can use .rows(sparse=False) to include empty rows for row in sheet.rows(): print(row) # [Cell(r=0, c=0, v='TEXT'), Cell(r=0, c=1, v=42.1337)]
NOTE: Iterating the same Worksheet instance multiple times in parallel (nested for for instance) will yield unexpected results, retrieve more instances instead.
Note that dates will appear as floats. You must use the convert_date(date) method from the corresponding Workbook instance to turn them into datetime.
print(wb.convert_date(41235.45578)) # datetime.datetime(2012, 11, 22, 10, 56, 19)
Converting a workbook to CSV:
import csv from pyxlsb2 import open_workbook with open_workbook('Book1.xlsb') as wb: for name in wb.sheets: with wb.get_sheet_by_name(name) as sheet: with open(name + '.csv', 'w') as f: writer = csv.writer(f) for row in sheet.rows(): writer.writerow([c.v for c in row])
Non exhaustive list of things that are currently not supported:
- Style and formatting WIP
- Rich text cells (formatting is lost, but getting the text works)
- Encrypted (password protected) workbooks
- Comments and other annotations
- Writing (out of scope)
