Python办公自动化，五分钟掌握openpyxl操作！

>>> from openpyxl import Workbook>>> wb = Workbook()

>>> from openpyxl import load_workbook>>> wb2 = load_workbook('test.xlsx')

wb = load_workbook(filename='large_file.xlsx', read_only=True)wb = Workbook(write_only=True)

>>> ws = wb.active

>>> ws1 = wb.create_sheet("Mysheet") # insert at the end (default) # or >>> ws2 = wb.create_sheet("Mysheet", 0) # insert at first position # or >>> ws3 = wb.create_sheet("Mysheet", -1) # insert at the penultimate position

>>> ws3 = wb["New Title"]

>>> print(wb.sheetnames) ['Sheet2', 'New Title', 'Sheet1']使用for循环遍历所有的工作表： >>> for sheet in wb: ... print(sheet.title)

>>> from tempfile import NamedTemporaryFile >>> from openpyxl import Workbook >>> wb = Workbook() >>> with NamedTemporaryFile() as tmp: wb.save(tmp.name) tmp.seek(0) stream = tmp.read()保存到文件： >>> wb = Workbook() >>> wb.save('balances.xlsx')保存为模板： >>> wb = load_workbook('document.xlsx') >>> wb.template = True >>> wb.save('document_template.xltx')

>>> c = ws['A4']

>>> ws['A4'] = 4 >>> c.value = 'hello, world'

>>> cell_range = ws['A1':'C2']

>>> # set date using a Python datetime >>> ws['A1'] = datetime.datetime(2010, 7, 21) >>>>>> ws['A1'].number_format 'yyyy-mm-dd h:mm:ss'

>>> # add a simple formula >>> ws["A1"] = "=SUM(1, 1)"

>>> ws.merge_cells('A2:D2') >>> ws.unmerge_cells('A2:D2') >>>>>> # or equivalently >>> ws.merge_cells(start_row=2, start_column=1, end_row=4, end_column=4) >>> ws.unmerge_cells(start_row=2, start_column=1, end_row=4, end_column=4)

>>> colC = ws['C'] >>> col_range = ws['C:D'] >>> row10 = ws[10] >>> row_range = ws[5:10]

&gt;&gt;&gt; for row in ws.iter_rows(min_row=1, max_col=3, max_row=2): ...for cell in row: ...print(cell) <cell sheet1.a1><cell sheet1.b1><cell sheet1.c1><cell sheet1.a2><cell sheet1.b2><cell sheet1.c2></cell></cell></cell></cell></cell></cell>

&gt;&gt;&gt; for col in ws.iter_cols(min_row=1, max_col=3, max_row=2): ... for cell in col: ... print(cell) <cell sheet1.a1><cell sheet1.a2><cell sheet1.b1><cell sheet1.b2><cell sheet1.c1><cell sheet1.c2></cell></cell></cell></cell></cell></cell>

>>> ws = wb.active >>> ws['C9'] = 'hello world' >>> tuple(ws.rows) ((, , ), (, , ), (, , ), (, , ), (, , ), (, , ), (, , ), (, , ), (, , ))

&gt;&gt;&gt; tuple(ws.columns) ((<cell sheet.a1>, <cell sheet.a2>, <cell sheet.a3>, <cell sheet.a4>, <cell sheet.a5>, <cell sheet.a6>, ... <cell sheet.b7>, <cell sheet.b8>, <cell sheet.b9>), (<cell sheet.c1>, <cell sheet.c2>, <cell sheet.c3>, <cell sheet.c4>, <cell sheet.c5>, <cell sheet.c6>, <cell sheet.c7>, <cell sheet.c8>, <cell sheet.c9>))</cell></cell></cell></cell></cell></cell></cell></cell></cell></cell></cell></cell></cell></cell></cell></cell></cell></cell>

>>> for row in range(1, 40): ... ws1.append(range(600)) >>> for row in range(10, 20): ... for col in range(27, 54): ... _ = ws3.cell(column=col, row=row, value="{0}".format(get_column_letter(col)))

>>> from openpyxl.utils import get_column_letter >>> ws.insert_rows(7)>>> row7 = ws[7]>>> for col in range(27, 54): ... _ = ws3.cell(column=col, row=7, value="{0}".format(get_column_letter(col)))Worksheet.insert_cols()操作类似。Worksheet.delete_rows()和Worksheet.delete_cols()用来批量删除行和列。

for row in ws.values:for value in row:print(value)

>>> for row in ws.iter_rows(min_row=1, max_col=3, max_row=2, values_only=True): ... print(row) (None, None, None)(None, None, None)
