What is a CSV file?

CSV stands for Comma-Separated Values. It's a plain-text format used to store tabular data, like a spreadsheet or database table. Each line is a row of data, and each value within a row is separated by a delimiter (comma by default). CSV is supported by Excel, Google Sheets, LibreOffice, and effectively every database and programming language.

Convert tab-separated text to CSV

Spreadsheet copy-paste produces tab-separated text. Pipe it through the converter:

text
Name	Email	Department
John Smith	john@company.com	Engineering
Jane Doe	jane@company.com	Marketing
Bob Wilson	bob@company.com	Sales

Output as RFC 4180-compliant CSV:

csv
Name,Email,Department
John Smith,john@company.com,Engineering
Jane Doe,jane@company.com,Marketing
Bob Wilson,bob@company.com,Sales

Fields containing commas, quotes, or newlines are wrapped in quotes and double-quoted as required by the spec.

Common use cases

Plain-text addresses → import into Mailchimp, HubSpot, or other ESPs.
Spreadsheet data
Clipboard → Excel/Sheets when source is unstructured text.
Database imports
CSV is the lingua franca of MySQL, Postgres, and ETL pipelines.
Log processing
Tab-separated server logs → CSV for analysis tools.
Data cleaning
Trim whitespace, normalize delimiters, handle messy inputs.
API responses
