我对python真的很陌生,但是我想从xlsx获取python给定单元格的颜色。我戴着读取xlsx的零件,但是如何获得A3电池的背景色呢?
import xlrd
workbook = xlrd.open_workbook('67.xlsx')
worksheet = workbook.sheet_by_name('Oldal1')
# read a cell
cell = worksheet.cell(2,2)
#print cell
print cell.value
答案 0 :(得分:1)
Always a solution out there, somewhere in the deep ocean of SO:
def getBGColor(book, sheet, row, col):
xfx = sheet.cell_xf_index(row, col)
xf = book.xf_list[xfx]
bgx = xf.background.pattern_colour_index
pattern_colour = book.colour_map[bgx]
#Actually, despite the name, the background colour is not the background colour.
#background_colour_index = xf.background.background_colour_index
#background_colour = book.colour_map[background_colour_index]
return pattern_colour
Oh, wait. this is even better!

这是完整的代码:
from xlrd import open_workbook
wb = open_workbook('cel_lis.xls', formatting_info=True)
sh = wb.sheet_by_name('Sheet1')
def getBGColor(book, sheet, row, col):
xfx = sheet.cell_xf_index(row, col)
xf = book.xf_list[xfx]
bgx = xf.background.pattern_colour_index
pattern_colour = book.colour_map[bgx]
#Actually, despite the name, the background colour is not the background colour.
#background_colour_index = xf.background.background_colour_index
#background_colour = book.colour_map[background_colour_index]
return pattern_colour
print("The RGB value of the cell is: {}".format(getBGColor(wb, sh, 0, 0)))
输出:
The RGB value of the cell is: (255, 0, 0)
注意:
我使用了类型为
.xls
的工作表,其名称为cel_lis.xls
名为Sheet1
的工作表,其中第一个单元格A
具有Red
背景颜色。

要获得颜色name
,可以使用webcolors
:
from webcolors import rgb_to_name
rgb_Col = getBGColor(wb, sh, 0, 0)
print("The RGB value of the cell is: {} which is equivalent to {}".format(rgb_Col, rgb_to_name(rgb_Col)))
输出:
The RGB value of the cell is: (255, 0, 0) which is equivalent to red

先前建议的解决方案仅适用于xls
文件,不适用于xlsx
文件。这产生一个NotImplementedError: formatting_info=True not yet implemented
。 Xlrd
库仍未更新为不适用于xlsx
文件。因此,您每次必须Save As
并更改格式,这可能对您不起作用。
这是使用xlsx
库的openpyxl
文件的解决方案。 A2
是我们需要找出其颜色代码的单元格。
import openpyxl
from openpyxl import load_workbook
excel_file = 'color_codes.xlsx'
wb = load_workbook(excel_file, data_only = True)
sh = wb['Sheet1']
color_in_hex = sh['A2'].fill.start_color.index # this gives you Hexadecimal value of the color
print ('HEX =',color_in_hex)
print('RGB =', tuple(int(color_in_hex[i:i+2], 16) for i in (0, 2, 4))) # Color in RGB
