CSV Engine vs DeepTable

CSV Engine is a web tool for cleaning and validating uploaded spreadsheets before export. It maps source columns to reusable templates, sanitizes values, detects duplicates, previews row-level failures, and can export only records that pass configured rules. Uploads use drag and drop, with automatic detection of delimiters, encodings, and headers. Column mapping supports aliases and fuzzy matching, and mappings can be saved per template. Listed cleanup includes whitespace trimming, casing normalization, email checks, phone parsing, and date fixes. Duplicate matching can use multiple fields and merge strategies, with conflicts reviewed before commit. Templates preserve schemas, field types, and validation rules for reuse. One credit processes up to 1,000 rows, including validation, deduplication, and export. The Free plan provides five credits per month and three active templates; the Starter plan is $15 a month billed annually. One-off credit packs are also available, beginning at $8, paid once, with credits that never expire. Pro includes email support with a 24-hour response; its developer API is listed as coming soon.

DeepTable is a cloud service that converts human-formatted Excel spreadsheets into clean, relational tables suitable for SQL workflows. Its LLM-powered engine interprets spreadsheet structure, relationships, merged cells, complex layouts, and visual formatting. The API accepts Excel .xlsx uploads up to 100MB and can return SQLite, Parquet, or CSV output. Every output value includes a reference to its source cell, allowing values to be traced back to the original sheet. Listed uses include RAG pipelines, AI agents processing business spreadsheets, SaaS spreadsheet ingestion, and enterprise internal tools. Developers can use TypeScript, Python, or Go libraries, or the command-line tool; API and Linux are listed platforms. The provider says uploaded spreadsheets and processing results are not used to train or fine-tune AI models. Users choose retention periods and may delete data, which is encrypted in transit and at rest. DeepTable is in private beta, with pricing on request.
