What CSV Engine is
CSV Engine is a cloud-based web tool for turning uploaded spreadsheets into production-ready data through column mapping, sanitization, validation, deduplication, and export. It accepts drag-and-drop CSV uploads, detects delimiters, encodings, and headers, and supports files described as handling up to millions of rows. Users can map source columns to templates using aliases and fuzzy matching, then save mappings for reuse. Cleanup options include trimming whitespace, normalizing casing, validating email addresses, parsing phone numbers, and fixing dates. Duplicate checks can use one or more fields, with merge strategies and conflict review before committing. A row preview flags failures, and exports can be limited to records that pass the user's rules. Templates preserve schemas, field types, and validation rules across imports. One credit processes up to 1,000 rows, including validation, deduplication, and export. The site describes the tool as useful for clerks, freelancers, no-code builders, and product, operations, and data teams.
