Comma-separated values (CSV) Format: A Simple Definition and Overview

What is Comma-separated values? How does it work and what does it do? This page aims to provide a clear and concise explanation of the CSV data format, commonly known as Comma-separated values.

Definition of Comma-separated values (CSV)

Comma-separated values (CSV) is a commonly used data format that allows the storage and exchange of tabular data in a plain text form. In a CSV file, each line represents a data record, and within each line, fields are separated by commas. This format ensures easy parsing and manipulation of data across different platforms and applications.

How does Comma-separated values work?

CSV files consist of rows and columns, just like a traditional spreadsheet. Each column represents a specific attribute or piece of information, while each row contains a set of related data. The commas serve as delimiters, ensuring the separation between fields and allowing easy identification of individual data values.

Being a plain text format, CSV files are human-readable and can be opened, edited, and manipulated using a wide range of software applications. The simplicity and universality of CSV make it a preferred choice for data exchange between different systems, programming languages, and databases.

Key features and benefits of Comma-separated values

Simplicity: CSV files use a straightforward structure, with data values separated by commas, making it easy to understand and work with.
Compatibility: The CSV format is platform-agnostic and supported by almost all spreadsheet applications and database systems, ensuring seamless data exchange.
Ease of use: The plain text nature of CSV allows for quick and easy data entry and editing using simple text editors.
Flexibility: CSV files can be easily imported and exported to and from various applications, making it convenient for data migration and integration.
Efficiency: Due to their compact size and simplified structure, CSV files consume less storage space and computational resources.

Why Assessing Comma-separated values Skills Matters

Our Customers Say

I was at WooliesX (Woolworths) and we used Alooba and it was a highly positive experience. We had a large number of candidates. At WooliesX, previously we were quite dependent on the designed test from the team leads. That was quite a manual process. We realised it would take too much time from us. The time saving is great. Even spending 15 minutes per candidate with a manual test would be huge - hours per week, but with Alooba we just see the numbers immediately.

Shen Liu, Logickube (Principal at Logickube)

We get a high flow of applicants, which leads to potentially longer lead times, causing delays in the pipelines which can lead to missing out on good candidates. Alooba supports both speed and quality. The speed to return to candidates gives us a competitive advantage. Alooba provides a higher level of confidence in the people coming through the pipeline with less time spent interviewing unqualified candidates.

Scott Crowe, Canva (Lead Recruiter - Data)

How can you accurately assess somebody's technical skills, like the same way across the board, right? We had devised a Tableau-based assessment. So it wasn't like a past/fail. It was kind of like, hey, what do they send us? Did they understand the data or the values that they're showing accurate? Where we'd say, hey, here's the credentials to access the data set. And it just wasn't really a scalable way to assess technical - just administering it, all of it was manual, but the whole process sucked!

Cole Brickley, Avicado (Director Data Science & Business Intelligence)

I wouldn't dream of hiring somebody in a technical role without doing that technical assessment because the number of times where I've had candidates either on paper on the CV, say, I'm a SQL expert or in an interview, saying, I'm brilliant at Excel, I'm brilliant at this. And you actually put them in front of a computer, say, do this task. And some people really struggle. So you have to have that technical assessment.
