CSV
A CSV is a plain spreadsheet file where each row is a line and each column is separated by a comma.
CSV stands for comma-separated values. It is the simplest form of a spreadsheet: plain text, one row per line, with commas between the columns. Excel, Google Sheets and almost every other tool can open and save CSV. Because it is so plain, it is the common language that programs use to pass tables to each other.
To make a CSV, build your table in Excel or Google Sheets with a header row, then use Save As or Download and pick CSV. Keep one item per row. Keep the header names simple. If a cell contains a comma, the spreadsheet tool handles the quoting for you.
On fad.fyi, a CSV is how you feed a product list. Only the title column is required. You can add price, link, image, category and description. Your fad then shows matching products as cards in the chat. You can also upload any other CSV as a normal file source.
