Convert CSV & Excel Tables into Markdown, JSON, HTML & SQL
Transforming raw spreadsheet rows (CSV, TSV, or Excel copy) into formatted Markdown tables for GitHub, JSON objects for web apps, semantic HTML tables for CMS platforms, or SQL INSERT scripts for database migrations usually requires writing tedious custom scripts. Our client-side Table Transformer performs instant multi-format conversions.
