CSV → JSON

POST /api/csv-to-json1 quota unit per call · cache hits free

Convert CSV files to a JSON array of objects via HTTP. RFC 4180 parsing with quoted fields, embedded commas, and escapes. Header row → object keys.

Reads RFC 4180-style CSV (with quoted fields, doubled-quote escapes, and embedded commas/newlines) and emits a JSON array. The first row is treated as the header — each subsequent row becomes an object keyed by header name. All values are emitted as JSON strings (CSV does not carry types). If your downstream wants numbers or booleans, parse them client-side or use `json-format` afterwards with a transformation step. Custom delimiters (TSV with `\t`, semicolons for European spreadsheets) are supported via the `delimiter` option.

Inputs

Name	Type	Default	Description
csv*	file	—	The CSV document.
prettyPrint	boolean	false	Indent the JSON output with two spaces.

Response

Modes: json. Cache: yes (24h TTL).

Every response carries x-cache (HIT / MISS / BYPASS), x-cache-signature (stable across identical inputs), and the rate-limit headers listed below.

Quota & limits

Cost per call	1 unit against the 10,000-unit monthly quota. Cache hits are free — only cache misses decrement.
Burst limit	200 requests per rolling minute, shared across all tools.
Max request size	`5 MiB` (base64 inflates file payloads ~33% — the limit applies to the decoded bytes).
Max response size	`20 MiB`
Timeout	5s wall clock.
Rate-limit headers	`X-RateLimit-Limit`, `X-RateLimit-Remaining`, `X-RateLimit-Burst-Limit` on every response; `X-Quota-Warning` once 80% of the monthly quota is spent; `Retry-After` on 429s.

Errors

Errors are JSON with an error string; schema failures add a details object (Zod's flattened field errors).

Status	When	Body
400	Input fails the tool's schema (wrong type, missing required field, malformed base64) or the file bytes can't be parsed as the expected format.	{ "error": "invalid inputs", "details": { "fieldErrors": { … } } }
401	Missing or invalid X-Api-Key / X-Account-Id headers (or no session when called from the browser).	{ "error": "unauthorized" }
404	Unknown tool id, or calling /api/* on the website hostname instead of api.xtract.bot.	{ "error": "not found" }
413	Request body over the tool's max request size, or an image header declaring more megapixels than the tool's pixel budget.	{ "error": "…exceeds maxRequestBytes…" }
415	Content-Type isn't application/json on the json-body transport.	{ "error": "unsupported content-type; expected application/json" }
429	Monthly quota or the 200/min burst limit exhausted. Check Retry-After and the X-RateLimit-* headers.	{ "error": "monthly quota exceeded", "monthRemaining": 0, … }
5xx	Conversion engine failure. Safe to retry; if it persists, the input is hitting a bug — please report it.	{ "error": "…" }
