The idea is to replicate almost all excel functionalities in Python, be it using a simple filter or a complex task of creating an array of data from the rows and crunching them to get fancy results. The approach followed here is to start from simple tasks and move to complex computational tasks.

I will encourage you to please replicate the steps yourself for your better understanding. The inspiration to create something like this came from the non-availability of a free tutorial which literally gives all. I heavily read and follow Python documentation and you will find a lot of inspiration from that site.

GitHub repo link. Initial step is to import excel files into DataFrame so we can perform all our tasks on it. Please follow the below link to download the dataset and ensure to save it in the same folder where you are saving your python file. We can import the spreadsheet data into Python using the following code:.

Should you require detailed explanation on the above, refer to the below medium article. We can use Python to scan files in a directory and pick out the ones we want. By default, the first sheet in the file is imported to the dataframe as it is. Default value is 0 i. We can either mention the name of the sheet s or pass an integer value to refer to the index of the sheet.

Unless explicitly mentioned, an index column is added to the DataFrame which by default starts from a 0. Using the arguments like skiprows and header we can manipulate the behavior of the imported DataFrame.

Using the usecols argument we can specify if we have import a specific column in our DataFrame. Its not the end of the features available however its a start and you can play around with them as per your requirements.

To view the first or last five rows.

Default is five, however the argument allows us to use a specific number. Gives the summary of DataFrame. Returns the dimensions of DataFrame. Descriptive reporting is all about data subsets and aggregations, the moment we are to understand our data a little bit we start using filters to look at the smaller sets of data or view a particular column maybe to have a better understanding. There exists three main methods to select columns:. The method used here is slicing using the loc function, where we can specify the start and end row separated by colon Remember, index starts from a 0 and not 1.

The input should always be a list We can use this method to replicate advanced filter function in excel. Sort data by a certain column, by default the sorting is ascending.In this tutorial, you will learn how to use Find and Replace in Excel to search for specific data in a worksheet or workbook, and what you can do with those cells after finding them.

We will also explore the advanced features of Excel search such as wildcards, finding cells with formulas or specific formatting, find and replace in all open workbooks and more. When working with big spreadsheets in Excel, it's crucial to be able to quickly find the information you want at any particular moment. Scanning through hundreds of rows and columns is certainly not the way to go, so let's have a closer look at what the Excel Find and Replace functionality has to offer.

Below you will find an overview of the Excel Find capabilities as well as the detailed steps on how to use this feature in Microsoft Excel, and older versions.

The following guidelines tell you how to find specific characters, text, numbers or dates in a range of cells, worksheet or entire workbook.

When you click Find NextExcel selects the first occurrence of the search value on the sheet, the second click selects the second occurrence, and so on. When you click Find AllExcel opens a list of all the occurrences, and you can click any item in the list to navigate to the corresponding cell. If you want to find cells that match a format of some other cell on your worksheet, delete any criteria in the Find what box, click the arrow next to Formatselect Choose Format From Celland click the cell with the desired formatting.

With Excel's Find and Replaceyou can only search in formulas for a given value, as explained in additional options of Excel Find. To find cells that contain formulas, use the Go to Special feature. If Microsoft Excel finds any cells that meet your criteria, those cells are highlighted, otherwise a message will be displayed that no such cells have been found.

To select all occurrences of a given value on a worksheet, open the Excel Find and Replace dialog, type the search term in the Find What box and click Find All. This will select all found occurrences both on the Find and Replace dialog and on the sheet. You can also delete all found cells or rows in one go.

For this, right-click the selected cells on a sheet and choose Delete from the context menu. Below you will find the step-by-step guidelines on how to use Excel Replace to change one value to another in a selected range of cells, entire worksheet or workbook.

The detailed steps follow below. If you've just used the Excel Find feature, then simply switch to the Replace tab. In the Find what box type the value to search for, and in the Replace with box type the value to replace with. Finally, click either Replace to replace the found occurrences one by one, or Replace All to swap all the entries in one fell swoop.

For additional Excel Replace features, click the Options button in the right-hand corner of the Replace tab. They are essentially the same as the Excel Find options we discussed a moment ago. To replace all occurrences of a specific value with nothingtype the characters to search for in the Find what box, leave the Replace with box blank, and click the Replace All button.

Enter the replacement character in the Replace with box, e. In the first part of this tutorial, we discussed how you can find cells with specific formatting using the Excel Find dialog. Excel Replace allows you to take a step further and change the formatting of all cells on the sheet or in the entire workbook. The use of wildcard characters, such as an asterisk and a question mark, in your search criteria can automate many find and replace tasks in Excel.

The following screenshot demonstrates how you can find all surnames that begin with " ad ":.

This is how you can replace all questions marks? If you have been closely following the previous sections of this tutorial, you might have noticed that Excel provides 2 different ways to interact with Find and Replace commands - by clicking the ribbon buttons and by using the keyboard shortcuts.You can find the location of the PyXLL log file in your pyxll. Build your Python functions that you intend to expose to Excel so that they can be run as separate functions outside of Excel.

This way, you can add tests for your code to ensure that it works as intended before trying it in Excel! If you do this, you can use whatever development tools you are already using without having to worry about connecting to Excel, and you can test changes before rolling them out to users who use your code in Excel. PyXLL comes with a Python package containing stub functions for all the pyxll functions and function decorators. Install this into your Python environment and you will be able to import and use code that references pyxll functions so that you can run and test them outside of Excel.

This package can be installed using pip. There is a community edition, but at the time of writing only the professional paid version supports attaching the debugger to Excel to allow you to debug your Python code running in PyXLL. Add the pycharm-debug egg to your pythonpath in your pyxll.

Depending on the version of PyCharm you are using you may find there are two eggs, one for Python 2. If there are two, make sure you use the correct one.

Recent versions of PyCharm just have a single egg that can be used for all versions of Python. Once the egg is added to your pythonpath, you will need to create a new run configuration in PyCharm.

That will open the configurations dialog. Give your new configuration a name and select the port that will be used to connect the PyCharm debugger to your code running in Excel. When the debugger is listening for connections you can connect to it from your Python code by calling:.

Note that when the code above is executed, it will pause the execution of your program until you continue in PyCharm. Once PyCharm is connected, you can set break points in the IDE and it will stop when reaching those lines.

You can then inspect variables and step though the code line by line. Once finished Eclipse will restart. You will have to change this filter to find the Excel process to attach to.

Once attached, you can now set breakpoints and the debugger will stop when they are hit. When a breakpoint is hit, you can then inspect variables and step through your code. If you are using an older version that does not have this option you should consider updating.
