Pandas Drop Rows With Condition

Use pandas.DataFrame.drop() method to delete/remove rows with condition(s). In my earlier article, I have covered how to drop rows by index from DataFrame, and in this article, I will cover several examples of dropping rows with conditions, for example, string matching on a column value. Alternatively, you can also achieve dropping rows by filtering rows and assigning them to another…

How To Delete Multiple Rows in Excel Sheet at Once

Delete multiple rows in Excel is a task that is done while performing data cleanup. The data cleanup process may be required when we get a dataset from the team we are working with or the vendor with whom we have corporate relations or we ourselves want to perform some predictive analysis in Excel. 

Why there is a need of deleting rows in Excel 

You need to remove a certain segment of data that is not important or there are endless blank cells that you need to delete to evaluate the data or cleaning up the datasheet and making it ready to structure the data. 

When you bring data from another source to the Excel worksheet, the imported data contains unwanted blank rows / columns in between and you want to erase them. 

You may want to delete multiple rows in Excel which are irrelevant data. When dealing with large data sets, you will need to delete multiple rows quickly to save time. As working with large data in the Excel sheet requires a lot of time performing the steps. It is necessary to know shortcuts and perform the steps faster to finish the task quickly.

Excel Features 

Microsoft Excel has so many useful features that project managers and analysts maintain the projects on MS Excel. Let us see some interesting features of Excel.

Add Header and Footer:

MS Excel enables you to keep the header and footer in the spreadsheet and when you take the print, you will see header and footer printed on the paper. Usually, company logo and taglines are part of headers and page number and company website URL is part of footer.

Find the order of text and replace it:

MS Excel helps us to locate the appropriate data (text, numbers, alphanumeric) in the workbook and also substitute the current data with a new one. For example, you are searching the text with “Adam”, you will see the cell containing the word and you can use the arrow key to go to the next result of the same word and so on. While formatting the data, you can use the replace feature to replace the found word one by one or all at once.

Filtration of data

Filtering is a fast and simple way to locate and run a subset of data within a range. Only rows that follow the requirements you define for a column are shown in the filtered set. MS Excel offers two filtering range commands: 

AutoFilter, which includes a filter by choice, for simple criteria;

Advanced Filter – to filter with more nuanced criteria.

Post filtering the data, it becomes easier to clean up the data using the “delete multiple rows” action with the options given in Excel.

Sorting of data

Data sorting is the method of organising data in a logical order. MS Excel helps you to sort data in ascending or descending order. You can also define the order of sorting the data. 

Formulae built-in:

Microsoft Excel includes several predefined, or built-in, formulas that are known as functions. 

Functions may be used to render basic or complex calculations. The most widely used function is the SUM function, which is used to add numbers to a set of cells. All complex mathematical formulas are available as built-in is used for quick calculation for larger datasets. Manually working on formulas is time consuming. Excel helps us to do the calculations quicker and easily.

Auditing Formula

Using formula auditing, we can graphically view or trace the relationship between cells and formulas with blue arrows. Precedents (cells that provide data to a specific cell) or dependents (cells that depend on the value in a specific cell) may be tracked.

Build Pivot Table and Charts (Pivot Table Report):

Creating a Pivot table for the data given in Excel is simpler. Arranging the dataset manually again is a question of correctness. There might be errors doing manual tasks. Excel gives functionality to generate Pivot within a fraction of a minute.

MS Excel helps us to construct various visual charts, such as bar graphs, pie-charts, line graphs, etc. This helps us interpret and compare data very quickly. Analysis related tasks are done easily generating charts from the given data in Excel. 

Security of Excel sheet / workbook using Password Protection

It helps users to protect their workbooks from unauthorised access to their details by using a password.

Add-ins / Macros

Excel offers a variety of add-ins to use certain tasks and calculations. One of them is Analysis ToolPack. For doing calculations of mathematical formulas and running regressions, this add-in is very useful. Running Macros using VBA editor in Excel works as a programming application. You can perform some repeated actions in your dataset using Macros. It is just awesome.

Insert and Delete Columns / Rows [step-by step guide]

There are 16384 total columns available in the Excel Worksheet. When you insert a new column, the total number of columns available in the Excel worksheet will not change. If the last columns (equivalent to the number of columns inserted) in the Excel worksheet are empty, the columns are deleted from the worksheet to accommodate the newly inserted Columns.

MS Excel is irreplaceable

Excel has strong capabilities to do analysis and execute regression models on the server. It also has a network sharing facility that allows the team to work on the same datasheet. It is a perfect tool for storing data that changes from time to time.

Google sheets, Mac OS Numbers are the spreadsheets with limited features and cannot beat MS Excel. There are scenarios where people use Windows OS only for MS Excel as other operating systems do not give its features in totality.

Knowing how to delete multiple rows in Excel at once is a simple and quick trick on your sleeve.
