Examples generating Excel Documents Using Python ' s XLWT

Here is some simple examples using Python's XLWT library to dynamically generate Excel documents.

Please note a useful alternative is EZODF, which allows you to generate ODS (Open Document Spreadsheet) files for LIBR Eoffice/openoffice. You can check the them out at:http://packages.python.org/ezodf/index.html

The simplest Example
import xlwt
workbook = xlwt.Workbook(encoding = ‘ascii‘)
worksheet = workbook.add_sheet(‘My Worksheet‘)
worksheet.write(0, 0, label = ‘Row 0, Column 0 Value‘)
workbook.save(‘Excel_Workbook.xls‘)


Formatting the Contents of a Cell
import xlwt
workbook = xlwt.Workbook(encoding = ‘ascii‘)
worksheet = workbook.add_sheet(‘My Worksheet‘)
font = xlwt.Font() # Create the Font
font.name = ‘Times New Roman‘
font.bold = True
font.underline = True
font.italic = True
style = xlwt.XFStyle() # Create the Style
style.font = font # Apply the Font to the Style
worksheet.write(0, 0, label = ‘Unformatted value‘)
worksheet.write(1, 0, label = ‘Formatted value‘, style) # Apply the Style to the Cell
workbook.save(‘Excel_Workbook.xls‘)


Attributes of the Font Object
Font.Bold = True # May be:true, False
Font.Italic = True # May be:true, False
Font.struck_out = True # May be:true, False
Font.underline = XLWT. Font.underline_single # May Be:underline_none, Underline_single, UNDERLINE_SINGLE_ACC, underline_double, UNDERLINE_ Double_acc
Font.escapement = XLWT. Font.escapement_superscript # May Be:escapement_none, Escapement_superscript, Escapement_subscript
font.family = XLWT. Font.family_roman # May Be:family_none, Family_roman, Family_swiss, Family_modern, Family_script, FAMILY_DECORATIVE
Font.charset = XLWT. Font.charset_ansi_latin # May Be:charset_ansi_latin, Charset_sys_default, Charset_symbol, CHARSET_APPLE_ROMAN, Charset_ansi_jap_shift_jis, Charset_ansi_kor_hangul, Charset_ansi_kor_johab, CHARSET_ANSI_CHINESE_GBK, CHARSET_ Ansi_chinese_big5, Charset_ansi_greek, Charset_ansi_turkish, Charset_ansi_vietnamese, CHARSET_ANSI_HEBREW, CHARSET_ Ansi_arabic, Charset_ansi_baltic, Charset_ansi_cyrillic, Charset_ansi_thai, Charset_ansi_latin_ii, CHARSET_OEM_ Latin_i
Font.colour_index =?
Font.get_biff_record =?
Font.height = 0x00c8 # C8 in Hex (in decimal) = ten points in height.
Font.Name =?
Font.outline =?
Font.shadow =?


Setting the Width of a Cell
import xltw
workbook = xlwt.Workbook()
worksheet = workbook.add_sheet(‘My Sheet‘)
worksheet.write(0, 0, ‘My Cell Contents‘)
worksheet.col(0).width = 3333 # 3333 = 1" (one inch).
workbook.save(‘Excel_Workbook.xls‘)


Entering a Date into a Cell
import xlwt
import datetime
workbook = xlwt.Workbook()
worksheet = workbook.add_sheet(‘My Sheet‘)
style = xlwt.XFStyle()
style.num_format_str = ‘M/D/YY‘ # Other options: D-MMM-YY, D-MMM, MMM-YY, h:mm, h:mm:ss, h:mm, h:mm:ss, M/D/YY h:mm, mm:ss, [h]:mm:ss, mm:ss.0
worksheet.write(0, 0, datetime.datetime.now(), style)
workbook.save(‘Excel_Workbook.xls‘)


Adding a Formula to a Cell
import xlwt
workbook = xlwt.Workbook()
worksheet = workbook.add_sheet(‘My Sheet‘)
worksheet.write(0, 0, 5) # Outputs 5
worksheet.write(0, 1, 2) # Outputs 2
worksheet.write(1, 0, xlwt.Formula(‘A1*B1‘)) # Should output "10" (A1[5] * A2[2])
worksheet.write(1, 1, xlwt.Formula(‘SUM(A1,B1)‘)) # Should output "7" (A1[5] + A2[2])
workbook.save(‘Excel_Workbook.xls‘)


Adding a Hyperlink to a Cell
import xlwt
workbook = xlwt.Workbook()
worksheet = workbook.add_sheet(‘My Sheet‘)
worksheet.write(0, 0, xlwt.Formula(‘HYPERLINK("http://www.google.com";"Google")‘)) # Outputs the text "Google" linking to http://www.google.com
workbook.save(‘Excel_Workbook.xls‘)


Merging Columns and Rows
import xlwt
workbook = xlwt.Workbook()
worksheet = workbook.add_sheet(‘My Sheet‘)
worksheet.write_merge(0, 0, 0, 3, ‘First Merge‘) # Merges row 0‘s columns 0 through 3.
font = xlwt.Font() # Create Font
font.bold = True # Set font to Bold
style = xlwt.XFStyle() # Create Style
style.font = font # Add Bold Font to Style
worksheet.write_merge(1, 2, 0, 3, ‘Second Merge‘, style) # Merges row 1 through 2‘s columns 0 through 3.
workbook.save(‘Excel_Workbook.xls‘)


Setting the Alignment for the Contents of a Cell
import xlwt
workbook = xlwt.Workbook()
worksheet = workbook.add_sheet(‘My Sheet‘)
alignment = xlwt.Alignment() # Create Alignment
alignment.horz = xlwt.Alignment.HORZ_CENTER # May be: HORZ_GENERAL, HORZ_LEFT, HORZ_CENTER, HORZ_RIGHT, HORZ_FILLED, HORZ_JUSTIFIED, HORZ_CENTER_ACROSS_SEL, HORZ_DISTRIBUTED
alignment.vert = xlwt.Alignment.VERT_CENTER # May be: VERT_TOP, VERT_CENTER, VERT_BOTTOM, VERT_JUSTIFIED, VERT_DISTRIBUTED
style = xlwt.XFStyle() # Create Style
style.alignment = alignment # Add Alignment to Style
worksheet.write(0, 0, ‘Cell Contents‘, style)
workbook.save(‘Excel_Workbook.xls‘)


Adding Borders to a Cell
# Note:while I was able to find these constants within the source code, on my system (using LibreOffice,) I am on Ly presented with a solid line, varying from thin to thick; No dotted or dashed lines.
Import XLWT
Workbook = xlwt. Workbook ()
Worksheet = Workbook.add_sheet (' My sheet ')
Borders = XLWT. Borders () # Create Borders
Borders.left = XLWT. Borders.dashed # May Be:no_line, THIN, MEDIUM, dashed, dotted, THICK, DOUBLE, HAIR, medium_dashed, thin_dash_dotted, MEDI um_dash_dotted, thin_dash_dot_dotted, medium_dash_dot_dotted, slanted_medium_dash_dotted, or 0x00 through 0x0D.
Borders.right = XLWT. Borders.dashed
Borders.top = XLWT. Borders.dashed
Borders.bottom = XLWT. Borders.dashed
Borders.left_colour = 0x40
Borders.right_colour = 0x40
Borders.top_colour = 0x40
Borders.bottom_colour = 0x40
style = XLWT. Xfstyle () # Create Style
Style.borders = borders # Add borders to Style
Worksheet.write (0, 0, ' Cell Contents ', style)
Workbook.save (' Excel_workbook.xls ')


Setting The Background Color of a Cell
import xlwt
Workbook = xlwt. Workbook ()
worksheet = workbook.add_sheet (' My sheet ')
pattern = xlwt. Pattern () # Create the pattern
Pattern.pattern = XLWT. pattern.solid_pattern # May Be:no_pattern, Solid_pattern, or 0x00 through 0x12
Pattern.pattern_fore_colour = 5 # May be:8 through 63. 0 = Black, 1 = white, 2 = Red, 3 = Green, 4 = Blue, 5 = Yellow, 6 = Magenta, 7 = Cyan, = maroon, + = Dark Green, 18 = Dark Blue, Dark Yellow, almost brown), = Dark Magenta, = Teal, = Light gray, Dark Gray, the list goes On ...
style = XLWT. Xfstyle () # Create the pattern
Style.pattern = pattern # Add pattern to style
Worksheet.write (0, 0, ' Cell Conte NTS ', style)
Workbook.save (' Excel_workbook.xls ')


Todo:things left to Document
- Panes -- separate views which are always in view
- Border Colors (documented above, but not taking effect as it should)
- Border Widths (document above, but not working as expected)
- Protection
- Row Styles
- Zoom / Manification
- WS Props?
