CSV API
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.)
