Hello Friends, In this blog tutorial, I am going to explain how to extract email addresses from bulk data in the CSV column.
let’s assume you have some data in the Excel column the same as shown in the below image.
It is easy to get all the email IDs from these CSV files if there are only 4-5 records but in the case of bulk records, it will be quite difficult to extract email addresses and use them for sending the email campaign.
Here, in this blog post, we are going to cover how I extract email addresses from a text string. How do I extract email addresses from the text in Excel? How do I extract data from a text string in Excel?
We will also see Extract email addresses from a text in Excel, Extract all emails from the text, Extract multiple emails, and addresses from Excel, and Extract email addresses from the Excel column.
so what is the procedure to extract email addresses from the CSV column where we have multiple data in the form of a string?
This is a quite simple process to extract email addresses from the raw CSV data, you just need to follow the procedure.
1. Install all the applications to develop this functionality.
Software required to develop this functionality are :
NetBeans IDE
Xampp Server
2. Create a new project name as ‘excel reader’ though you can name it as per your wish.
Now create a few files and folders as given in the below image.
3. Now copy and paste the below code into the respective files as shown in the file hierarchy.
index.php

Note: remember to make one upload folder inside the source project file.
Once you complete all the above procedures and run the code then you will get the option to select a CSV file after submitting the button.
you will see all the emails in the output result and you will also get an option for downloading the CSV file.
See the images below for the extracted email address.
