Python(Pandas/XlsxWriter)を使ってExcelファイルを操作してみる②

Last updated at Posted at 2016-05-20

今後はExcelファイルを読み込む編。

ついでにCSVファイルを読み込むバージョンも。

ファイルの出力についてはこちら

参照

Excelファイルを読み込む

# import lib
import pandas as pd

# read xlsx file
xlsFile = "hoge.xlsx"
sheetName = "hoge1"
xls_data = pd.read_excel(xlsFile, sheetname=sheetName)
print(xls_data)

CSVを読み込む

# import lib
import pandas as pd

# read csv file
csvFile = "fuga.csv"
csv_data = pd.read_csv(csvFile, encoding='utf-8')
print(csv_data)

おまけ

指定した位置のデータを読み込む

列指定

xls_data = pd.read_excel(xlsFile, sheetname="hoge1", parse_cols="A:H")

行指定

xls_data = pd.read_excel(xlsFile, sheetname="hoge1", skiprows=0, skip_footer=5)

行列指定したい場合は両方指定すればいい。A1:H5みたいに指定できればいいけど、それはできなさげ?
