DESCRIPTION

Converts CSV or TSV data into JSON, JSONL/NDJSON, or column-oriented arrays. RFC 4180 parser with type inference (booleans, integers, floats, ISO dates, null tokens) and configurable delimiter, quote char, header presence, column rename, drop columns, and whitespace trim. Outputs newline-delimited JSON (jsonl), a JSON array (json), or column-oriented arrays (ndarray). Use it as a CSV to JSON, CSV to NDJSON, TSV to JSON, or spreadsheet to JSON converter, data pipeline preprocessor, or LLM training-data prep step.

INPUT — request schema

property	type	description	req?
csv	string	Raw CSV / TSV text. Up to ~1MB recommended.	required
format	string	Output shape. 'jsonl' (default, newline-delimited JSON objects), 'json' (single JSON array), 'ndarray' (column-oriented arrays). enum: jsonl · json · ndarray	optional
delimiter	string	Field delimiter. Default ','. Use '\t' for TSV, ';' for European CSV, '\|' for pipe-delimited.	optional
quote_char	string	Quote character for fields containing the delimiter or newlines. Default '"'.	optional
has_header	boolean	Whether the first row is the header. Default true. If false, columns are named c1, c2, ...	optional
rename	object	Optional column-rename map, e.g. { 'first name': 'first_name', 'DOB': 'date_of_birth' }.	optional
drop_columns	array	Column names to drop from the output.	optional
infer_types	boolean	If true (default), parse booleans, integers, floats, ISO-8601 dates, and null tokens. If false, every value stays a string.	optional
null_values	array	Strings to coerce to JSON null. Default ['', 'null', 'NULL', 'NA', 'N/A'].	optional
trim	boolean	Trim leading/trailing whitespace from each field. Default true.	optional

OUTPUT — response shape

field	type	description
jsonl	string	Newline-delimited JSON string with one parsed CSV row per line; present when output format is jsonl.
data	array	Array of parsed row objects keyed by column name, with values coerced via type inference.
mime_type	string	MIME type of the converted payload, e.g. application/json or application/x-ndjson.
row_count	number	Number of data rows parsed from the input CSV, excluding the header row.
column_count	number	Number of columns detected in the parsed CSV after any drop/rename operations.
columns	array	Ordered list of final column names after header parsing and any rename or drop transforms.
format	string	Output format selected for the conversion, either json or jsonl.

EXAMPLES — two ways to call

EXAMPLE 1 · curl

curl -X POST https://x402.agentutility.ai/csv-to-jsonl \
  -H 'Content-Type: application/json' \
  -d '{ }'

first response = 402 Payment Required with payment requirements; sign + retry with X-PAYMENT.

EXAMPLE 2 · mcp

# Install the MCP package for this endpoint's cluster
npx -y @agentutility/mcp-<cluster>

# Required: EVM private key with USDC on Base
export X402_PRIVATE_KEY=0x...

# Then call the csv-to-jsonl tool from your MCP-aware agent.

MCP server handles payment automatically — your coding agent just calls the tool by name.
