Parse a delimited table and create JSON records while exposing header and data-shape issues for review.
Conversion works best when the first row contains unique field names and every later row follows the same column structure. Decide whether empty cells should become empty strings, null values or omitted fields. Values that look numeric, such as postal codes or long account identifiers, may need to remain strings.
CSV has many dialects. Embedded line breaks, escaped quotes, byte-order marks and inconsistent row lengths can change the result. Automatic type inference may corrupt identifiers or dates. Large files are limited by available browser memory.
Parsing is designed to happen locally, but business exports commonly contain personal or financial data. Use an approved device and anonymized samples whenever possible, and retain the source until the converted result has been verified.
