The Data Analyst's Guide to RFC 4180 and Clean CSVs

"Error: Line 4032 - Invalid Format"

CSV (Comma Separated Values) seems simple, but it is defined by a strict standard: IETF RFC 4180. Common violations that break database imports include:

1. Unescaped Quotes: "Notes": "He said "Hello"" (Breaks the parser).
2. Inconsistent Line Endings: Mixing CRLF (Windows) with LF (Linux).

The Solution: JSON as a Validator

When dealing with legacy data dumps, converting CSV to JSON is a powerful "Linting" strategy. Because JSON (defined in ECMA-404) is a much stricter format, the CSV to JSON Converter acts as a strict validator.

Expert Workflow

1. Export raw data from SQL.
2. Convert to JSON. If the tool errors, it will pinpoint the exact line violation (e.g., "Unexpected token at position 405").
3. Fix the source data.
4. Re-convert for the final import.

This "Round-Trip" validation prevents the partial-import disasters that corrupt database integrity.
