Excel to CSV Converter: Sheet & CSV Quality Audit

Convert Excel to CSV and audit the selected sheet for rows, columns, blanks, delimiter risk and export-readiness signals.

CSV has no universal schema or type system. Delimiter detection and type summaries are practical heuristics, while repairs create a new copy instead of silently altering the source. Excel conversion focuses on cell values and simple worksheets rather than promising perfect preservation of formulas, macros, charts, external links, formatting or every workbook feature.
