About TXT and CSV

Understanding how plain text files differ from CSV and when to convert between them.

TXT

What is TXT?

TXT (Plain Text) files contain raw text data with no formatting. Many applications export data as plain text files with various delimiters such as commas, tabs, semicolons, or pipes separating fields. These files are simple but require conversion to be opened correctly in spreadsheet applications.

CSV

What is CSV?

CSV (Comma-Separated Values) is the most widely supported format for tabular data. CSV files open directly in Excel, Google Sheets, and virtually any data analysis tool, making them the most portable format for sharing structured data.
