Python package "xlrd"
Purpose: Provide a library for developers to use to extract data from Microsoft Excel (tm) spreadsheet files. It is not an end-user tool.
Author: John Machin, Lingfo Pty Ltd (email@example.com)
Licence: BSD-style (see licences.py)
Versions of Python supported: 2.6, 2.7, 3.2+.
External modules required:
- The package itself is pure Python with no dependencies on modules or packages outside the standard Python distribution.
Outside the current scope: xlrd will safely and reliably ignore any of these if present in the file:
- Charts, Macros, Pictures, any other embedded object. WARNING: currently this includes embedded worksheets.
- VBA modules
- Formulas (results of formula calculations are extracted, of course).
- Autofilters, advanced filters, pivot tables, conditional formatting, data validation
Unlikely to be done:
- Handling password-protected (encrypted) files.
Particular emphasis (refer docs for details):
- Operability across OS, regions, platforms
- Handling Excel's date problems, including the Windows / Macintosh four-year differential.
- Providing access to named constants and named groups of cells (from version 0.6.0)
- Providing access to "visual" information: font, "number format", background, border, alignment and protection for cells, height/width etc for rows/columns (from version 0.6.1)
import xlrd book = xlrd.open_workbook("myfile.xls") print "The number of worksheets is", book.nsheets print "Worksheet name(s):", book.sheet_names() sh = book.sheet_by_index(0) print sh.name, sh.nrows, sh.ncols print "Cell D30 is", sh.cell_value(rowx=29, colx=3) for rx in range(sh.nrows): print sh.row(rx) # Refer to docs for more details. # Feedback on API is welcomed.
Another quick start: This will show the first, second and last rows of each sheet in each file:
OS-prompt>python PYDIR/scripts/runxlrd.py 3rows *blah*.xls
- On Windows: use the installer.
- Any OS: Unzip the .zip file into a suitable directory, chdir to that directory, then do "python setup.py install".
- If PYDIR is your Python installation directory: the main files are in PYDIR/Lib/site-packages/xlrd the docs are in the doc subdirectory, and there's a sample script: PYDIR/Scripts/runxlrd.py
- If os.sep != "/": make the appropriate adjustments.
- This package started life as a translation from C into Python of parts of a utility called "xlreader" developed by David Giffin. "This product includes software developed by David Giffin firstname.lastname@example.org."
