The application is responsible for importing and retrieving three months’ worth of closing price history for various stock symbols via an Excel spreadsheet import process, then exporting an Excel spreadsheet containing the new data.
In this post i will show you Laravel 8 Import Export CSV/EXCEL File Example. We will simple create import data to xls, csv file and also we will import data to database using csv file in laravel 8 application.
Using this example we can easily import-export and download the csv & excel file from the database using the maatwebsite/excel composer package. maatwebsite/excel provide easy way to import and export csv file in laravel 8 using database model.

In this tutorial, let’s discuss what data validation is and how it can be implemented in MS-Excel. Let’s start!!!
Data Validation is one of the features in MS-Excel which helps in maintaining the consistency of the data in the spreadsheet. It controls the type of data that can enter in the data validated cells.
Now, let’s have a look at how data validation works and how to implement it in the worksheet:
To apply data validation for the cells, then follow the steps.
1: Choose to which all cells the validation of data should work.
2: Click on the DATA tab.
3: Go to the Data Validation option.
4: Choose the drop down option in it and click on the Data Validation.
Once you click on the data validation menu from the ribbon, a box appears with the list of data validation criteria, Input message and error message.
Let’s first understand, what is an input message and error message?
Once, the user clicks the cell, the input message appears in a small box near the cell.
If the user violates the condition of that particular cell, then the error message pops up in a box in the spreadsheet.
The advantage of both the messages is that the input and as well as the error message guide the user about how to fill the cells. Both the messages are customizable also.
Let us have a look at how to set it up and how it works with a sample

C and C++ are the most powerful programming language in the world. Most of the super fast and complex libraries and algorithms are written in C or C++. Most powerful Kernel programs are also written in C. So, there is no way to skip it.
In programming competitions, most programmers prefer to write code in C or C++. Tourist is considered the worlds top programming contestant of all ages who write code in C++.
During programming competitions, programmers prefer to use a lightweight editor to focus on coding and algorithm designing. Vim, Sublime Text, and Notepad++ are the most common editors for us. Apart from the competition, many software developers and professionals love to use Sublime Text just because of its flexibility.
I have discussed the steps we need to complete in this blog post before running a C/C++ code in Sublime Text. We will take the inputs from an input file and print outputs to an output file without using
freopen file related functions in C/C++.

If you are familiar with C/C++then you must have come across some unusual things and if you haven’t, then you are about to. The below codes are checked twice before adding, so feel free to share this article with your friends. The following displays some of the issues:
The below code generates no error since a print function can take any number of inputs but creates a mismatch with the variables. The print function is used to display characters, strings, integers, float, octal, and hexadecimal values onto the output screen. The format specifier is used to display the value of a variable.
A signed integer is a 32-bit datum that encodes an integer in the range [-2147483648 to 2147483647]. An unsigned integer is a 32-bit datum that encodes a non-negative integer in the range [0 to 4294967295]. The signed integer is represented in twos-complement notation. In the below code the signed integer will be converted to the maximum unsigned integer then compared with the unsigned integer.

Syncfusion Excel (XlsIO) Library is a .NET Excel library that allows users to convert Excel documents to various file formats such as PDF, image, HTML, ODS, and JSON. Among them, the Excel-to-JSON conversion is supported from the 18.3 version onward. The resultant JSON files can be bound to any control in any platform. This is one of the major advantages for users.
In this blog, we are going to see how an Excel file can be converted to a JSON stream in C## using the Syncfusion XlsIO library. We’ll also look at the procedure to bind the JSON stream to a Syncfusion DataGrid control. The following options are available in the Excel to JSON conversion:
