I will convert CSV to jsonl or jsonl to CSV with validation

I will convert one UTF-8 CSV to JSONL, or one JSONL file to CSV, with up to 1,000 records and 20 fields. JSONL must contain flat objects with string values and identical fields; CSV needs unique nonempty headers and consistent columns. You receive the converted file and a short validation note. Unicode, quoted commas, multiline CSV values and empty strings are preserved. Your original stays unchanged. Field order may be standardized; numeric-looking values remain strings. No nested JSON, arrays, Excel workbooks, data enrichment, cleaning or type inference is included. Files are processed locally and results checked before delivery. Provide the file, desired direction and any formatting constraints. Contact me before ordering for larger or different inputs. One revision within the agreed scope and three-day delivery are included. Share only data you have permission to provide.
