Frequently Asked Questions
CSV (Comma-Separated Values) is a plain text format for tabular data where each row is a line and each column is separated by a comma. It is universally supported — every database, spreadsheet application, data science tool, and programming language can read and write CSV. It has no version incompatibility, no proprietary format, no required software, and can be opened in a plain text editor. This universality makes it the standard for data export and interchange.
Values are quoted when they contain a comma, a newline, or a double-quote character — all of which would otherwise be interpreted as CSV delimiters. For example, an address "123 Main St, Suite 4" must be quoted to prevent the comma from being read as a column separator. Our CSV parser handles quoted values correctly, including the edge case of escaped quotes inside quoted fields (represented as two consecutive double quotes: "").
Semicolon-delimited files (common in European countries where the comma is used as a decimal separator) are a TSV/DSV variant, not strict CSV. Our viewer expects comma-delimited data. To view semicolon files, do a find-and-replace to swap semicolons for commas before pasting, being careful not to replace semicolons that appear inside quoted fields.
