About the formats

What is CSV?

CSV (comma-separated values) is a plain-text format that stores tabular data, one row per line and fields separated by commas. It needs no special software: any text editor, spreadsheet application or database can read it. Because of its simplicity, CSV is the universal interchange format between databases, spreadsheets and other programs.

Use CSV whenever you need to move tabular data between systems, exporting a database, importing contacts or sharing a table with someone who uses different software. Choose CSV when plain, predictable data matters more than formatting.

What is Markdown?

Markdown is a lightweight markup language that lets you write formatted documents in plain text using simple symbols. The same file reads clearly as text and renders as styled HTML, making it popular for documentation, README files and notes. It is also widely used to feed clean text to large language models.

Use Markdown for content that should be readable as plain text but publishable with formatting, README files, documentation, wikis, notes and posts. Write it anywhere, and it stays usable forever because the source is plain text.
