CSV stores tabular data as plain text rows — common for spreadsheets, exports and ETL pipelines.
CSV uses commas or semicolons as delimiters with optional quoted fields for embedded commas. RFC 4180 conventions help interoperability but real-world files vary — European Excel often uses semicolon separators.
Validate headers and types before database import. Tentaco CSV↔JSON converters parse and preview locally, catching delimiter and encoding issues early.
