ODS to CSV Spreadsheet Converter
Convert every ODS worksheet to CSV. Repeated rows and columns and internal blank cells are preserved. Empty tails outside the last nonempty value are trimmed. Select a sheet to preview or download it. Stored numeric, date, time and boolean values take precedence over formatted display text. Formulas use cached values and are not recalculated; formatting, charts and merged layout are not exported. Spreadsheet applications may interpret CSV text as formulas.

Document parsing & data extraction pipeline
Parses common comma- or tab-delimited text with quoted cells, embedded separators, multiline values, and doubled quote marks. Local tools can transpose or reorder CSV data, create SQL text, and generate a basic XLSX worksheet with fitted column widths and an autofilter. The parser is permissive rather than a strict RFC 4180 validator; the XLSX output does not add styling, frozen rows, typed-value inference, or a general mojibake repair guarantee.

File size & structure constraints
ODS must be smaller than 50,000,000 bytes. Limits: 256 sheets, 1,000,000 expanded cells across sheets, 16,384 columns, 1,048,576 rows per sheet, 64 MiB CSV output or 128 MiB XLSX output, and 30 seconds including file reading. ODS also has the shared 100,000 ZIP-entry, 16 MiB XML, XML depth 128 and 1,000,000-node limits. JSON nesting can create at most 64 child-sheet levels; each XLSX cell is limited to 32,767 UTF-16 units. Encrypted ODS and XML DTDs are rejected. XLSX uses blue bold headers, a frozen header row, filters and estimated column widths between 10 and 60. Widths are estimates from text length, not native font measurements. Each preview page has 16,000 characters; downloads contain the full output. Source sheet names, JSON keys and technical markers are not translated. Native Excel / LibreOffice compatibility is not certified.
