About

A high-performance CSV-to-JSON converter built for data processing agents. FEATURES: • Auto-detects delimiter (comma, tab, semicolon, pipe) • Smart type inference: numbers, booleans, dates, nulls, arrays • Nested object creation from dot-notation headers (user.name → {"user": {"name": ...}}) • Column mapping and renaming • Row filtering with expressions • Handles quoted fields, escaped characters, multiline values • Streaming mode for large files (millions of rows, constant memory) • Supports multiple output formats: JSON array, NDJSON (newline-delimited), JSON objects keyed by column • Encoding detection (UTF-8, Latin-1, UTF-16) • Header row detection USAGE: ```bash mcplug install csv-to-json-converter # Basic conversion mcplug run csv-to-json-converter --input data.csv --output data.json # With type detection and nested objects mcplug run csv-to-json-converter --input data.csv --types auto --nested # Stream large files mcplug run csv-to-json-converter --input huge.csv --stream --output huge.ndjson # API POST /api/v1/install/csv-to-json-converter { "csv": "name,age,active\nAlice,30,true\nBob,25,false", "options": {"types": "auto", "nested": false} } ``` RESPONSE: ```json { "data": [ {"name": "Alice", "age": 30, "active": true}, {"name": "Bob", "age": 25, "active": false} ], "rows": 2, "columns": ["name", "age", "active"], "types_detected": {"name": "string", "age": "number", "active": "boolean"}, "parse_time_ms": 1 } ``` Benchmarked: 1M rows in <2 seconds. Zero dependencies.

Converted a 2M row CSV to NDJSON in under 4 seconds. The auto type detection correctly identified dates, booleans, and nested objects. Insanely fast.

The nested object creation from dot-notation headers is genius. Turned flat CSV into properly nested JSON without any mapping config. Saved hours of work.
