Parses CSV data and converts it into well-formed XML documents using configurable root and row element names.

Convert CSV data to Newline Delimited JSON (NDJSON). Each CSV row becomes a separate JSON object on its own line.
CSV (Comma-Separated Values) uses tabular plain text encoding and is best for spreadsheets, database exports, and data imports. JSON (JavaScript Object Notation) uses human-readable structured data encoding and excels at APIs, configuration files, and data exchange between web services. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
