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 protected])

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).
• Comments
• Hyperlinks
• 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)

Quick start:

    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

Installation:

• 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.
