python使用pandas处理excel文件转为csv文件的方法示例

import pandas
 
df = pandas.read_excel("/***/***.xlsx")
 
df.columns = [内部为你给你的excel每一列自定义的名称]（比如我给我的excel自定义列表为：
["url","productName","***"，。。。,"***"]）

df["url"] = df["url"].str.replace("http", "https")
 
df["***"] = df["***"].str.replace("\n", " ")
 
df["stract_content"] = df["url"].str[-6:]

df.drop_duplicates().fillna("").to_csv("/***/***.csv", index=False, encoding="utf-8", sep="\3")

with codecs.open("result.csv", "w", encoding="utf-8") as fw:
  for i in final_res:
    fw.write(u"\3".join([j if isinstance(j, unicode) else str(j).decode("utf-8") for j in i]) + "\n")

df = pandas.DataFrame(my_list)
df.columns = ["col1", "col2", ...]
df.to_excel("result.xlsx", index=False, encoding="utf-8")

with codecs.open("result.csv", "w", encoding="utf-8") as fw:
  for i in final_res:
    fw.write(u"\3".join([j if isinstance(j, unicode) else str(j).decode("utf-8") for j in i]) + "\n")
 
with pandas.ExcelWriter('result.xlsx') as ew:
  pandas.read_csv("result.csv", sep='\3').to_excel(ew, index=False, header=["文件名", "query调用时间", "调用ip", "调用类型", "query结束时间", "行序号", "top5 sku", "文件总耗时"], sheet_name="result", encoding="utf-8")

with codecs.open("result.csv", "w", encoding="utf-8") as fw:
  for i in final_res:
    fw.write(u"\3".join([j if isinstance(j, unicode) else str(j).decode("utf-8") for j in i]) + "\n")
 
df = pandas.read_csv("result.csv", sep="\3")
df.columns = ["col1", "col2", ...]
df.to_excel("result.xlsx", index=False, encoding="utf-8")
