Learning All about CSV Files or Comma Separated Values

Are you interested to learn about what the term CSV actually means and how it connects to the world of computations and symbols that end up building data strings for websites all over the globe? Please read this article to find out everything you would want to know.

We will provide you with some information about the CSV files and extensions and how you can use it to your advantage when creating unique command strings for programs down the line. However, before going any further let us first define the term CSV.

Definition Of Terms

The term CSV refers to comma-separated values or any delimited text files that use commas to separate and divide a string of significant character symbols into individual sets. A CSV file can store both numbers and text expressed as plain figures.

Each line of the file also consists of more fields that are separated by commas. This particular punctuation mark serves as a field separator that can also serve as a file name for this particular format.

The CSV file format is not the standard format used in normal text. The idea of separating fields with commas is pretty clear. However, it can be confusing when a certain field contains commas as part of the string. This is similar to embedded line breaks with commas as part of the character string.

Thus, CSV files may not be able to handle such a large amount of data. Most of the time, developers also use other punctuation marks in conjunction with the comma to divide it from the string as a unique element. An example of these additional punctuation marks in a string would be the quotation.

However, this does not solve everything. Some strings may require the use of quotation marks as part of the character set as well in order to be implemented. In this case, CSV files can also make use of escape characters and sequences for implementation.

Other Connotations

CSV can also refer to delimited or separated file formats and character strings that use different punctuation marks as a field separator. Here are some examples:

  • The Semicolons
  • Tab and space-separated values

A delimiter that is invisible from the character string much like “tab”, keeps the format simple and easy to understand. Different CSV files are still usually given the .csv extension despite having other punctuation marks as field separators.

Many of the applications that accept CSV files have the embedded option to accept either the delimiter character or the quotation marks. Semicolons are also used as a field separator in some European countries.

The Exchange Of Data

Data files with comma-separated values are commonly used by consumers, business entities as well as various scientific applications. The most common use among these would be as an integral part of a tabular representation of data. The data exchange occurs usually between and among programs that operate within non-compatible formats. Most of these non-compatible formats are undocumented or copyrighted properties.

This usually works because of the support of so many programs for many variations of the CSV format used for data importation.

For instance, users may need to execute a data transfer from one database program to another. One or the other database may use spreadsheets to store data in either proprietary or undocumented format.

When this happens, the program user may export the file using a CSV extension which can then be imported into the spreadsheet of another program to be converted into a compatible file.

Specific Definitions

Standard specifications have been proposed for CSV files by RFC 4180. These are the definitions commonly used. However, within the regular field, the term CSV usually refers to many types of file formats.

This is why the term CSV can refer to files that include the following:

  • Plain text with Unicode character strings.
  • Records (one record per line)

Records are usually divided into different fields that are separated by delimiters which can refer to single characters or commands such as space or tab option. The usual punctuations can also serve as delimiters (Commas, semicolons, quotations, etc.).

In addition, every record usually has the same field sequence.

Within these parameters, there are many known variations used. This is why there’s no usual specification for every file that is claimed to be a CSV. In addition to this, most of the applications supporting these file types recognize the first few lines of the file as a preview and have specifications regarding the delimiter characters and quotes.

If any of these variations fall beyond the scope of the supporting program used, programmers and coders are usually called upon to work on the file manually, using a text editor. These professionals often write scripts to reformat the whole file if and when necessary.

Closing Statement

These are just some of the important facts you need to know about comma-separated values within files. With these significant pieces of data, we hope that you will be able to create your own CSV string sooner rather than later.
