What is a CDN and How Does It Improve Speed?

In today's digital world, every website owner wants his site to load fast and users to have a good experience. If a website is slow, visitors leave it quickly, which affects both traffic and business. The solution to this problem is CDN (Content Delivery Network) . But many people still do not understand what CDN is and how it increases the speed of our website. In this blog, we will learn step by step what CDN is, how it works and why it is important for modern websites. What is CDN? The full form of CDN is Content Delivery Network . It is a distributed network in which servers are spread across the world. These servers store copies of your website's content (such as images, videos, CSS files, JavaScript files, PDFs, etc.). When a user opens your site, the content is delivered to him from the nearest server. This makes the site load faster because the data does not travel from a far-off server. How does a CDN work? The working of a CDN is simple but the concept is powe...

Excel Automation Tips for Faster Workflow

Microsoft Excel is a tool that is used in almost every office, company, school and government office. But many people use Excel only for basic purposes - like creating tables, adding and subtracting, or entering data. Actually, Excel is a powerful tool in which with the help of automation, you can do hours of work in just a few seconds.

In this blog, we will tell you the most useful Excel automation tips that will make your workflow several times faster, smarter and easier – that too without any coding.

What is Excel Automation?
Automation means creating a system that performs repetitive tasks automatically. With automation in Excel, you can create reports, update data, prevent mistakes and save time in a few clicks.

1. Automate calculations with Excel formulas
Excel's biggest strength is its formulas. If you use formulas like SUM, AVERAGE, IF, VLOOKUP, COUNTIF correctly, then many tasks can be done automatically.

Example:

  • =SUM(A2 :A100 ) → sum of the entire column

  • =IF(B2>50, "Pass", "Fail") → Automatic result

  • =VLOOKUP("Product A", A2 :C100 , 2, FALSE) → Find the price of a product

2. Prevent incorrect data with Data Validation
If you do not want a user to enter incorrect data, like not filling text in a column where a number is required, then you can use Data Validation .

How to do:

  1. Select the column

  2. Go to Data > Data Validation

  3. Place a condition like “Whole Number” or “List”

  4. Also add an Error Alert so that a message is displayed if an incorrect entry is made

Advantage:

  • There will be fewer mistakes

  • The data will be clean and accurate

3. Highlight data with Conditional Formatting
If you want specific values, like marks above 90 or sales above ₹10,000, to appear in red or green, use Conditional Formatting .

How to do:

  1. Select the data

  2. Home > Conditional Formatting > Highlight Cell Rules

  3. Enter your bet and choose a colour

Advantage:

  • Important information is visible at a glance

  • The report looks more professional

4. Automate reports with Pivot Table
Pivot Table is one of the most powerful features of Excel that allows you to create summaries of thousands of data in just seconds.

How to make:

  1. Select all data

  2. Insert > Pivot Table

  3. Add fields to rows and columns

  4. Add options like COUNT or SUM to values

Advantage:

  • Report ready in minutes

  • Data analysis with Drag & Drop

  • Easy filtering and sorting

5. Fill data automatically with Flash Fill
Flash Fill works like magic. If you want to create a full name from first name in one column and last name in another, Excel recognizes it automatically.

Example:
Column A: Ravi
Column B: Kumar
In Column C, type “Ravi Kumar” once
and then do Flash Fill below – the rest of the cells will be filled automatically

How to do:

  1. Type an example

  2. Click in the cell below

  3. Press Ctrl + E (or Home > Fill > Flash Fill)

6. Automate repetitive tasks with macros
If you do the same task over and over again in Excel – like formatting a sheet, renaming it, adding a border – you can record it and create a macro.

How to do:

  1. View > Macros > Record Macro

  2. Give a name and click OK

  3. Now whatever work you do will be recorded

  4. Stop recording

  5. Now you can run Macro repeatedly with just one button

Note: Save the file in .xlsm format for macro

7. Use Excel Table for Automatic Range
If you create an Excel Table (Ctrl + T), formulas, colors and formatting are automatically copied when you add a new row. This makes data handling easier.

Advantages:

  • header automatic

  • Auto Filter is available

  • The formula applies to the entire column

  • Ease of reporting

8. Import and clean data with Power Query
If you bring external data into Excel – like another sheet, a website, a CSV file – Power Query lets you automatically clean and format that data.

How to do:

  1. Data > Get & Transform > Get Data

  2. Select the source of the data

  3. Delete, rename unwanted columns in Query Editor

  4. Do “Close & Load”

Advantage:

  • No need to clear data again and again

  • Reports are updated in one click

9. Create Drop-down Lists for Quick Entry
If you need to fill out a form and want people to choose from a fixed list of options – like “Male”, “Female”, “Other” – then create a drop-down.

How to make:

  1. Type the options in a column

  2. Go to where you want the drop-down

  3. Select Data > Data Validation > List

  4. Select Range and click OK

Advantage:

  • Data will remain the same

  • Entry will be quick and accurate

10. Insert Alert or Message in Excel (Using IF + Msg)
If you want to display a message based on the value in a cell – like “Target Achieved” or “Low Sales” – you can do it using the IF formula.

Example:
=IF(B2>10000, "Good", "Improve")
This will automatically change the message in the cell

11. Speed ​​up work with keyboard shortcuts.
Automation doesn't just mean formulas, shortcut keys also make work many times faster:

  • Ctrl + T → Create a table

  • Ctrl + Shift + L → Apply Filter

  • Alt + E + S + V → Paste Special

  • Ctrl + Arrow Keys → Move quickly

  • F2 → Edit a cell

  • Ctrl + Space → Select the entire column

  • Shift + Space → Select the entire row

12. Automation is also possible in Google Sheets.
If you use Google Sheets instead of Excel, then features like Data Validation, Conditional Formatting, Pivot Tables, and Macros are also available for automation.

13. Use Excel Add-ins
Microsoft Excel also has many add-ins that help in automation such as:

  • Power BI

  • Solver

  • Kutools for Excel (third party)

  • Office Scripts (Web Excel рдоें)

Conclusion
If you are using Excel only for addition and subtraction, then you are missing its real power. With the above automation tips, you can use Excel as a smart assistant that will speed up your work, reduce errors and save time.
