【已解决】python解析excel文件并读取其中的sheet和row和column的值

Excel crifan 2183浏览 0评论

折腾:

【已解决】把本地的音频字幕等数据存储到本地MongoDB数据库中

期间,需要去用python去读取和解析一个excel文件,并读取其中的内容,

包括包括多个sheet,以及每个sheet中行row和列column的单元格cell的值:

crifan python excel xlsx

python read excel xlsx

Python-Excel 模块哪家强?

  • xlwings

  • openpyxl

  • pandas

  • win32com

  • xlsxwriter

    • 只能写入

  • DataNitro

  • xlutils

此处已经可以基本确定用:openpyxl

但是为了想要顺带再去学学panda的话,去搜搜:

Creating Excel files with Python and XlsxWriter — XlsxWriter Documentation

Python操作excel的几种方式–xlrd、xlwt、openpyxl | 文强的个人空间

  • xlrd:用来读取很方便

  • openpyxl:虽然功能很强大,但是操作起来感觉没有xlwt方便

xls – Reading xlsx files using Python – Stack Overflow

  • openpyxl不错

  • xlrd也不赖

openpyxl – A Python library to read/write Excel 2010 xlsx/xlsm files — openpyxl 2.5.0 documentation

Python Excel Tutorial: The Definitive Guide (article) – DataCamp

看下来:

复杂点的:panda+excel解析器,比如panda+openpyxl

简单点的:openpyxl或xlrd

很久之前用过:xlrd

现在为了尝试新的,且不太麻烦,还是先直接用:openpyxl吧。

参考官网文档:

用 openpyxl 处理 xlsx 文件 – 李林克斯

想要去写代码,但是发现对于excel中的列的表示不清楚:

【已解决】Excel中把列名的表示方式从数字换成英文字母

然后就可以去使用L13这种写法去读取cell的值了。

代码:

# parse excel file

excelFullfilename = "/Users/crifan/dev/dev_root/xxx/xxx018.3.28_forDebug.xlsx"

wb = load_workbook(excelFullfilename)

logging.info("wb=%s", wb)

# sheetNameList = wb.get_sheet_names()

# logging.info("sheetNameList=%s", sheetNameList)

ws = wb[u"绘本"]

logging.info("ws=%s", ws)

rows = ws.rows

columns = ws.columns

是可以正常执行的:

现在需要去搞清楚,一共有多少行,然后每行循环去处理。

去找找api文档:

https://openpyxl.readthedocs.io/en/stable/index.html

-》

openpyxl package — openpyxl 2.5.0 documentation

Index — openpyxl 2.5.0 documentation

openpyxl.cell.cell module — openpyxl 2.5.0 documentation

搜:

sheet

workbook

openpyxl.packaging.workbook module — openpyxl 2.5.0 documentation

Openpyxl  get current sheet max row

python – Is it possible to get an Excel document’s row count without loading the entire document into memory? – Stack Overflow

row_count = sheet.max_row

column_count = sheet.max_column

-》

openpyxl.worksheet.worksheet module — openpyxl 2.5.0 documentation

-》

https://openpyxl.readthedocs.io/en/stable/api/openpyxl.worksheet.worksheet.html#openpyxl.worksheet.worksheet.Worksheet.max_row

“max_column

The maximum column index containing data (1-based)

Type:

int

max_row

The maximum row index containing data (1-based)

Type:

int “

找到了。

然后PyCharm中再想要去查看源码,也是可以看到合适的匹配出的代码的:

然后就可以去写代码读取值了:

from openpyxl import Workbook, load_workbook

StorybookSheetTitle = u"绘本"

EnglishStorybookRootPath = "/Users/crifan/dev/dev_rootxxx"

ExcelFilename = "xxx资源2018.3.28_forDebug.xlsx"

ExcelFullFilename = os.path.join(EnglishStorybookRootPath, ExcelFilename)

AudioFilePathPrefix = EnglishStorybookRootPath

# parse excel file

wb = load_workbook(ExcelFullFilename)

logging.info("wb=%s", wb)

# sheetNameList = wb.get_sheet_names()

# logging.info("sheetNameList=%s", sheetNameList)

ws = wb[StorybookSheetTitle]

logging.info("ws=%s", ws)

# process each row in excel

for curRowNum in range(realContentRowStartNum, ws.max_row + 1):

    logging.info("-"*30 + " row[%d] " + "-"*30, curRowNum)

    hasAudioFileColNumCellValue = ws.cell(row=curRowNum, column=HasAudioFileColNum).value

    logging.info("col[%d] hasAudioFileColNumCellValue=%s", HasAudioFileColNum, hasAudioFileColNumCellValue)

    audioFilePathColNumCellValue = ws.cell(row=curRowNum, column=AudioFilePathColNum).value

    logging.info("col[%d] audioFilePathColNumCellValue=%s", AudioFilePathColNum, audioFilePathColNumCellValue)

对于excel文件:

输出:
