What is CSV, and how is it used and created?

CSV, or comma-separated values, is a simple and widely used file format for storing data in a table-like structure. It is essentially a text file that uses commas to separate values and lines to separate records. 

Think of it as a spreadsheet saved as a text file, where each line represents a row, and a comma separates each value. The great thing about CSV is that it can be easily imported into spreadsheet software like:

  • Excel
  • Google Sheets
  • Apple Number
CSV File

Creating a CSV file is a breeze. All you need is a spreadsheet program like Excel or Google Sheets, and then you simply save the file as a CSV. 

This file format is commonly used for data exchange between different applications, making it a versatile and valuable tool for businesses and individuals. Whether managing a customer database or analyzing sales data, CSV can help you organize and make sense of large amounts of information.

CSV is a user-friendly file format that can help simplify data storage and exchange. It's an easy way to organize and share data without the need for complex software or programming skills.

What is Excel and how is it used and created?

Excel is a powerful software that helps users organize, calculate and manipulate data in a spreadsheet format. Think of it like a virtual notebook perfect for keeping track of information, such as:

  • Numbers
  • Names
  • Dates, etc.

Excel works by organizing data in a grid of rectangular boxes called "cells," which are arranged in rows and columns.

This popular software can be used for a wide range of tasks, from simple calculations to complex data analysis. Excel provides various tools for formatting and sorting data, as well as performing calculations and generating charts and graphs. It is commonly used in industries like:

  • Finance
  • Accounting
  • Marketing, etc.

Creating an Excel document is easy. Simply open the program and start entering data into the cells. You can then format the data, apply formulas, and create visual representations of the data using charts and graphs. Excel is a great tool for managing and analyzing large amounts of information, making it a valuable asset for businesses and individuals alike.

Excel is a versatile and user-friendly program that can help you organize and make sense of your data. Whether managing a budget or analyzing sales data, Excel is essential for any data-driven project.

Differences between TXT, CSV, and XLS file types

Text files (TXT files), CSV files, and Excel (or excel spreadsheets) are  ways to store data, work on, and use data depending on your need:

(1) Text File (TXT) - Text files have plain text and are commonly created with PC NotePad (PC) or TextEdit (Mac). If you paste content into a text file, all the styles and formatting are stripped out, leaving you with plain text. This makes it easy to copy and paste data without formatting issues. If you paste spreadsheet data into a TXT file, it's separated by tabbed spaces.

(2) Comma Separated Value File (CSV) - Like Tetx file, a CSV file also contains plain text but is more versatile because it can be opened on any operating system, using any text editor, as well as in spreadsheet applications, like Excel. If you copy-paste spreadsheet data into a CSV file, it opens separated by commas.

(3) Excel Spreadsheet (XLS) - Excel files or excel spreadsheets can only be opened by other spreadsheet applications, like OpenOffice Calc, Google Sheets, etc., but they have lots of formatting options, ways to calculate data through functions and ways to present data visually through charts and tables. Unlike CSV, information pasted into a spreadsheet is separated into cells, rows, and columns.

Take a look at the figure examples below to see how the same information is displayed in a text file, CSV file, and Excel spreadsheet:

How can you troubleshoot and overcome common issues in CSV to Excel conversion?

Common Issue #1- CSV File Opening in One Column in Excel

When opening a CSV file in Excel, it can be frustrating to find that all the data appears in a single column. This happens because Excel uses the list separator set in your Windows Regional settings to split data into columns. If the delimiter used in a particular CSV file differs from the default separator, the file will open in one column.

Thankfully, there are several possible solutions to this problem. While some methods involve VBA macros or changing your Windows settings, we'll focus on a quick and easy fix that won't affect any other applications on your computer.

To fix this issue:

  1. Use Excel's built-in Text to Columns feature. This tool allows you to split the data in a single column into separate columns based on a specific delimiter.
  2. Select the column that contains the data you want to split.
  3. Click on the Text to Columns button in the Data tab.
  4. Follow the prompts to choose the delimiter that matches your CSV file and separate the data into columns.

When a CSV file opens in a single column in Excel, it's likely due to a difference in delimiters. Fortunately, Excel provides a handy tool to split the data into columns and make it more readable. Using the Text to Columns feature, you can quickly and easily fix this issue without changing your Windows settings or using any complicated macros.

Common Issue #2 - Fixing CSV Date Format Issues in Excel

The days and months are swapped, or some dates are even changed to text. This can be frustrating, but don't worry - there are solutions.

The problem usually occurs because the CSV file's date format differs from the default date format set in your operating system. This can cause Excel to misinterpret the dates and format them incorrectly.

The good news is that there are several solutions you can try, depending on the specific problem you're facing. These may include:

  1. Changing the date format
  2. Using Excel's Text to Columns feature
  3. Using a formula to reformat the dates

With these simple fixes, you can convert your CSV file to Excel with the correct date formatting.

Common Issue #3 - Preventing Excel from Using Scientific Notation

When working with CSV files in Excel, you may encounter a problem where long numbers are automatically formatted into scientific notation, making them hard to read and understand. This occurs when a number exceeds Excel's limit of 15 digits of precision

The software automatically converts these numbers to scientific notation to fit the limitation, leaving you with an unsightly format like 2.34B+08 instead of the original.

Luckily, there are ways to prevent Excel from automatically converting your numbers to scientific notation. One solution is to import the numbers as text, allowing you to keep the original formatting. 

Alternatively, you can change the Number format directly in Excel, allowing you to display the full number without any scientific notation. This can be particularly useful if you need to perform calculations or analysis on these numbers, as scientific notation can make it harder to work with the data.

How can you improve your skills in converting CSV to Excel?

Converting CSV files to Excel can be simple, but sometimes it can be tricky. If you want to improve your skills in converting CSV to Excel, you can do a few things:
