CSV API

healthy 4,621 Subscribers

A fast, fully-local CSV data toolkit: parse CSV into typed row objects (RFC-4180), compute per-column statistics (count, unique, type and top values, and for numeric columns min, max, mean, median and sum), remove duplicate rows by all or a subset of columns, sort by a column with numeric-aware ordering, and filter rows by a condition (equals, not-equals, greater/less than, contains, starts-with, empty, not-empty). Every endpoint accepts input via the query string or the request body, up to 2 MB, and returns both row objects and a CSV string. Pure server-side compute, no third-party upstream, so responses are instant and always available. Ideal for data wrangling, ETL, analytics preparation, spreadsheet tooling and data cleaning. (For plain CSV to JSON conversion, see the oanor JSON API.)

JSON API

A fast, fully-local JSON and CSV toolkit: validate JSON (with a clear error message, type and size), pretty-print and format it (with optional deep key-sorting), minify it (reporting bytes saved), and convert between CSV and JSON — RFC-4180 CSV parsing with automatic value typing, and JSON arrays to CSV. Every endpoint accepts input via the query string or the request body (up to 1 MB). Pure server-side compute, no third-party upstream, so responses are instant and always available. Ideal for data pipelines, ETL, webhooks, config tooling and developer utilities.

Exercises API

A complete exercise and workout database covering 870+ exercises: search and filter by target muscle, required equipment, category, difficulty level, force type and mechanic, fetch a single exercise with step-by-step instructions, primary and secondary muscles and demonstration images, pull a random exercise matching any filter, and read all available facet values to build filter UIs. Every endpoint accepts input via the query string or the request body and returns lean, predictable JSON. Pure server-side data (no third-party upstream), so responses are instant and always available. Ideal for fitness and gym apps, workout planners, personal-trainer tools and health platforms.

Wikipedia API

A fast, clean wrapper over the official Wikimedia APIs covering every Wikipedia language: full-text article search with snippets, lead-section summaries (extract, short description, thumbnail and canonical URL), "on this day" historical events, births, deaths and holidays for any calendar day, and a random-article endpoint. Every endpoint takes a "lang" parameter (en, de, fr, es, simple, zh and any other Wikipedia language) and accepts input via the query string or the request body. Returns lean, predictable JSON with HTML stripped and entities decoded — no scraping, no rate-limit juggling, no client-side parsing. Ideal for chatbots and RAG pipelines, trivia and "this day in history" apps, knowledge panels, education and research tools.
