问题 I have a simple problem but I can't find a simple solution: I have an Excel file (always the same), with several WorkSheets that non-IT coworkers want to be able to update so that it also updates the Google Charts (or other chart API you can advise me) webpage. (By the way, I only need a certain part of each worksheet so if you know a way to extract only what I need that would be great :) ) I would like to avoid having server-side operation but it's maybe not possible since I want to read a

csv & xlsx files import to pandas data frame: speed issue

由 眉间皱痕 提交于 2019-12-06 03:13:34
问题 Reading data (just 20000 numbers) from a xlsx file takes forever: import pandas as pd xlsxfile = pd.ExcelFile("myfile.xlsx") data = xlsxfile.parse('Sheet1', index_col = None, header = None) takes about 9 seconds. If I save the same file in csv format it takes ~25ms: import pandas as pd csvfile = "myfile.csv" data = pd.read_csv(csvfile, index_col = None, header = None) Is this an issue of openpyxl or am I missing something? Are there any alternatives? 回答1: xlrd has support for .xlsx files, and

I have an application which reads an .xlsx file and displays the content to the user. The application works fine on a windows environment. I deployed the .war file of this web app on tomcat6 on a ubuntu server. I also copied the .xlsx files on the server. The path of the files in the code is correct. But the line FileInputStream file = new FileInputStream(new File(FileName)); XSSFWorkbook workbook = new XSSFWorkbook(file); gives an error java.lang.reflect.InvocationTargetException org.apache.poi.POIXMLException: java.lang.reflect.InvocationTargetException org.apache.poi.xssf.usermodel

ImportError: Install xlrd >= 0.9.0 for Excel support when using pd.readexcel to read .xlsx file : never happened before

Something strange is going on. Just today when trying to read in a dataframe from an xlsx file: import pandas as pd df = pd.read_excel('vlnew.xlsx',sheet_name='Sheet1') I am getting the following error: ImportError: Install xlrd >= 0.9.0 for Excel support I am fully aware that plain and simple the instructions are to install xlrd, but I should not have to install xlrd when I was never getting this error before, and also, xlrd only applies to the old .xls file format. I am using .xlsx. I can't understand why today all of a sudden this error is popping up. This is very strange indeed, at least

JAVA数据库建表工具类

前言： 在实际项目中会遇到建主题数据库的工作(主题数据库定义：面向特定的学科和应用领域，由若干的逻辑相关的数据源按照统一的标准规范整合形成，具有系统性和完整性，并通过统一的系统提供一站式服务的数据库。)，就是批量按照需求建表，此时就需要一些代码辅助操作。 思路： 1、相关人员会提供表结构文件，类似如下图： 2、提取有用信息，单独建立excle文件，如下图： 3、使用代码把信息读取出来， 4、生成SQL语句， 具体实现： 1、准备java代码需要依赖的jar包： <!-- https://mvnrepository.com/artifact/org.apache.poi/poi --> <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi</artifactId> <version>4.1.0</version> </dependency> <!-- https://mvnrepository.com/artifact/org.apache.poi/poi-ooxml --> <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi-ooxml</artifactId> <version>4.1.0</version> </dependency>

Write dataframe to excel with a title

由 天涯浪子 提交于 2019-12-05 18:17:58
I would like to print out a dataframe in Excel. I am using ExcelWriter as follows: writer = pd.ExcelWriter('test.xlsx') df = DataFrame(C,ind) # C is the matrix and ind is the list of corresponding indices df.to_excel(writer, startcol = 0, startrow = 5) writer.save() This produces what I need but in addition I would like to add a title with some text (explanations) for the data on top of the table ( startcol=0 , startrow=0 ). How can I add a string title using ExcelWriter? You should be able to write text in a cell with the write_string method, adding some reference to XlsxWriter to your code:
