What is CSV and How Does it Work?
CSV stands for Comma Separated Values, which is a way of formatting data in order to be stored in a text file. Data is stored as a series of delimited values, with each value being separated by a comma. For example, if a person stored their first name, last name, and age in a CSV file, the line might look something like this: “John,Smith,27”. Here, each value is separated by a comma, with the first value representing the first name, the second value representing the last name, and the third value representing the age.
CSV files are often used to store large amounts of data, as they are easy to read and manipulate. They can be opened in any text editor, and can be imported into a variety of programs, such as spreadsheets and databases. CSV files are also often used to transfer data between different programs, as they are a universal format that can be read by any program.
Once the data is in an array, it can be manipulated and used in various ways. For example, it can be used to create charts and graphs, or to filter and sort the data. Additionally, the data can be used to create custom functions and algorithms that can be used to analyze the data in more detail.
Another issue that can arise when converting CSV to an array is dealing with entries that contain commas. In this case, the entry must be enclosed in quotation marks to ensure that the comma is not interpreted as a delimiter. Additionally, any quotation marks within the entry must be escaped with a backslash to prevent them from being interpreted as the end of the entry.
