post/file-convert/v1/data_convert1 credit
Deterministic data-format conversion: CSV ↔ JSON ↔ XML ↔ YAML ↔ Excel(xlsx) (any direction; tabular targets need tabular-shaped input — clean error otherwise). 200k-row cap. Output delivery: each produced file ≤10MB comes inline as base64 (files[].file_b64); 10-50MB comes as a one-time download token (files[].download_path, 30min TTL); >50MB total is rejected.
