CSV to ODS runs through our table engine, turning one delimited text table into an OpenDocument spreadsheet without formulas or styling from a source workbook.
From real runs
| Element | Result | What happens |
|---|---|---|
| Rows and columns | Kept | The account, zip, total, date, and note columns were written in the same order to content.xml. |
| Quoted delimiters | Kept | The note value containing a comma and quote survived as comma, quote "kept" in the ODS XML text. |
| Numeric-looking IDs | Changed | ZIP 02134 became 2134 in our API run because scalar coercion treated it as a number. |
| Numbers | Kept | Totals 1234.50, -19.95, and 88 became numeric-looking values in the generated OpenDocument sheet. |
| Dates | Changed | ISO date strings were converted to timestamp-like values with date styling in the ODS package. |
| Unicode | Kept | The accented name Café Norte was present in the OpenDocument content output. |
| Workbook features | Lost | CSV has no formulas, multiple sheets, merges, charts, comments, or styles for ODS to preserve. |

/convert/csv-to-xlsx when the recipient specifically works in Microsoft Excel.Our table engine coerces scalar values while parsing CSV. Store sensitive identifiers with a nonnumeric prefix or clean them after conversion.
No. A CSV file contains one table, so the output workbook has one sheet for the parsed rows.
Quotes used for CSV syntax are not preserved as syntax. The tested note value kept the literal quote inside the cell text.
