If you are interested in Excel, you most likely are pursuing a career or hobby in regards to data. By now, you probably have realized you can do anything in Excel, and there are millions of resources out there to help you through it.
Package like xlwings links any Excel with Python macros. Packages like Pandas, takes data into tabular format and also has customized filtering of rows or columns for complex data analysis. Packages like Matplotlib, Plotly enables to create different plots - line plot, Scatter plot, Heat map for finding the correlation b/w different parameters. まえがき Excel Advent Calendar 2014 に空きがあったので、 前々からやりたかった「xlwings」の記事を書いた。 ちなみに僕はBlogあるので、Qiitaに何もなかったからいい機会だ。 xlwin.
You now need to progress, which means leaving Excel behind and moving into Databases and code. I recommend starting with Python. While it is code, it is easier than most.
The xlwings add-in is the preferred way to be able to use the Run main button, RunPython or UDFs.Note that you don’t need an add-in if you just want to manipulate Excel by running a Python script. 在上篇文章中重点介绍了Xlwings中的App，Book等API知识点。本次推文将继续上次的知识点，将继续介绍Xlwings中Sheet和Range等API相关的知识，并展示一些小例子，让大家可以跟着教程进行学习。 顺便说一下，本人使用的Xlwings的版本号为：0.19.1. Xlwings is a BSD-licensed Python library that makes it easy to call Python from Excel and vice versa. It works with Microsoft Excel on Windows and macOS.

Again, millions of resources online to get you started. Python is very popular, and has a package feature which allows smart people to do the hard work, and you just reap the benefits. Packages are like formulas in Excel - you don’t need to understand the background code to use them.
This allows you do things like image recognition and machine learning. Relatively easily.
But before we get ahead of ourselves, let’s start small. I got bored of the online tutorials, as I learn by doing (particularly if it can be related to work or something I find useful). The best way I found to learn it, was get Python to work with Excel. This way, you can start to see the benefit of Python without being scared away from things like dataframes and CSV files.
This allows you to talk to Excel very easily.
(I’m assuming you have already figured out the basics of things like Pip Install and have your packages all sorted out. If not, I understand this is a tricky bit and something I haven’t even fully figured out. The best solution is to download the fantastic free editor, Pycharm. This does all the hard work for you - no more annoying pip download. Find a tutorial on how to get started. )
Install XLWINGS using PIP or Pycharm.
Assuming you have a workbook called “forecast” in your root directory (or the directory with your script if using Pycharm) this will write in Cell A1.
Why not create a loop as well, to list data from a python list into Excel?
What I showed you above is very basic. However just like Excel, you can google and look at the XLWINGs website to figure out how do pretty much anything.
For example you can launch macros with Python, add in formulas, formatting charts etc. Why not store data in Excel from Python, sync excel to google sheets and create a live dashboard of data?

I will write more blogs in the future about useful Python tools for Excel.
