Let's get started.
CSV file stands for Comma Separated Value file.CSV file is a type of plain text file that is a common format used for data exchange between different applications.

5. Each line in the CSV file is called a record and this acts as a row of data in a table.
6. Leading and trailing space of character between comma field separators are ignored and trimmed out.
7. The fundamental concept of separating fields from commas is simple, but when field data contain commas as well then the situation becomes complicated. Because there is no standard method for doing this. But general solutions look like this:
The solution for this is: Enclose the field in double-quotes.

CSV is data and database file extensions.Some other file of this types are : .dat, .db, .sql, .tar, .mdb etc.

1 It is used to import and export the data from one application to another.
2 It is a platform-independent file. You can create a CSV file in a Windows environment and can open the same file in Linux and Mac environments.
3 Large number of applications can open this file easily. Some applications that can open this file are excel, office, google sheets, LibreOffice, GenScriber, OpenOffice Calc, Fresh Books, Mobi systems OfficeSuite, etc.
4 It can be easily imported into the database.
5 Importing data into Excel takes up more memory, whereas importing CSV files takes significantly less memory, and reading those CSV files in excel will be much faster.
A database program that keeps data which cannot be read by other applications then, in this case, that proprietary format can export into CSV format and save it as a CSV file, and later it can be easily imported into another spreadsheet program and database application.

CSV Files and XLSX Files are different. Differences between CSV File and XLSX File are as follows.
|CSV File||XLSX File|
|CSV stands for Comma Separated Values. It is a plain text file that contains a series of data separated by delimiters generally commas.||
XLSX stands for Excel Microsoft Office Open XML Format Spreadsheet file. It is Microsoft Excel Spreadsheet used for storing, organizing, and analyzing the data.
|CSV files only contain delimited data and we cannot use formulas on them.||In XLSX files, we can store data as well as can perform formatting, use formula, and macro, and generates Pivot Table, and VBA code on it.|
|CSV files can be opened and edited by all text editors.||XLSX cannot be edited or opened by text editors.|
|CSV generally consumes less memory than xlsx files.||XLSX consumes more memory while importing data.|
|Data of CSV will only be text or number.||Data of XLSX may contain text, numbers, charts, and graphs|
|Less Complicated than XLSX files.||More Complicated than CSV files|
|In CSV no operations on data can be performed||In XLSX operations on data can be performed.|
Ans: Because XLSX files are compressed files. If there are many repeated data in excel then XLSX files are generally smaller than CSV files.
