#sort

Operate on text line by line. The transform endpoint sorts lines (natural / numeric-aware, ascending or descending, case-insensitive), removes duplicate lines, reverses their order, numbers them, trims whitespace and drops blank lines — and the operations chain in the order you list them, so trim → remove blanks → dedupe → sort happens in a single call. The count endpoint reports line statistics: total, blank, non-blank, unique and duplicate counts plus the longest, shortest and average line length. Perfect for cleaning up lists and logs, deduplicating, preparing data and tidying pasted text. Pure local computation — no key, no third-party service, instant; up to 500,000 characters via POST. Live, nothing stored. 3 endpoints. Distinct from word wrapping, sorting of JSON lists and CSV tooling.

Sort a list — or an array of objects by one of its keys — the way you actually want. Natural (alphanumeric) ordering puts file2 before file10 and v1.9 before v1.10, the way humans expect; alphabetical, numeric and by-length orderings are also built in, each ascending or descending, with an optional case-insensitive mode. Items can be plain strings (comma- or newline-separated) or a JSON array; for objects, give the property to sort by and rows missing it go last. Perfect for file and version lists, leaderboards and tables, tidying user input and any UI that shows sorted data. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. Distinct from set operations and CSV tooling.

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.)
