Supports: ODS
.ods files and they convert with the same settings.ODS (OpenDocument Spreadsheet) is the native spreadsheet format of LibreOffice Calc and Apache OpenOffice Calc. It is one part of the OpenDocument Format family, which OASIS approved as a standard in May 2005 and ISO/IEC adopted as ISO/IEC 26300 in November 2006. Under the hood an .ods file is a ZIP archive of XML documents describing the cells, formulas, charts, and styling — an open, vendor-neutral alternative to Excel's XLSX.
Because ODS is an open standard, modern Excel (2013 and later), Google Sheets, and Apple Numbers can all open it directly — so you rarely need to convert just to read the data. The reason to convert is usually about how the file will be shared, displayed, or printed, not edited:
Note that these are rendering conversions: xconvert lays the spreadsheet out onto pages or an image. They produce a fixed, read-only version for sharing — they are not a way to keep editing the numbers in Excel. If you need a still-editable Excel workbook, open the ODS in Excel or Google Sheets and use "Save As → XLSX" there.
| Target | Type | Editable after? | Keeps live formulas? | Best for |
|---|---|---|---|---|
| Fixed-layout document | No (read-only) | No — values only | Sharing and printing an exact, frozen layout | |
| DOCX / DOC | Word document | Text yes, as a table | No — values only | Pasting the table into a written report |
| PNG / JPG | Raster image | No | No — pixels only | Slides, chat, wikis, web embeds |
| EPUB / MOBI | Reflowable e-book | No | No — values only | Reading on e-readers and tablets |
| PS / EPS | PostScript | No | No — values only | Print servers and prepress pipelines |
| XLSX (in Excel) | Spreadsheet | Yes | Yes | Continuing to edit the numbers (use Excel, not this tool) |

ODS stands for OpenDocument Spreadsheet, the native spreadsheet format of LibreOffice Calc and Apache OpenOffice Calc and part of the ISO/IEC 26300 OpenDocument standard. Internally it is a ZIP archive of XML files holding the cells, formulas, charts, and formatting. It opens in LibreOffice Calc, Apache OpenOffice Calc, Google Sheets, Apple Numbers, and — since the 2013 version — Microsoft Excel, which can open and save .ods directly, though Microsoft notes some formatting may differ between ODS and XLSX.
No — this tool renders an ODS into fixed-layout documents and images (PDF, DOCX, images, EPUB, PS), not into another editable spreadsheet. PDF or an image freezes the sheet so a recipient can view and print it but not recalculate it. If you specifically need an editable XLSX workbook or a raw CSV of the data, the simplest route is to open the ODS in Excel, Google Sheets, or LibreOffice Calc and use "Save As" to export XLSX or CSV there, since those apps read ODS natively.
No — and this is the key trade-off to understand. Converting ODS to PDF, DOCX, or an image captures the computed values your spreadsheet currently shows, but it does not carry over the live formulas behind them. The output is a snapshot, so editing a number in the result won't recalculate anything. If you need the formulas to keep working, keep an ODS or XLSX copy and only treat the converted file as a sharing or printing copy.
Convert it to PDF. The most common reason a spreadsheet looks wrong on someone else's screen is that their app reflows columns, applies a different default font, or repaginates the print area. A PDF locks the page layout, fonts, gridlines, and page breaks exactly as rendered, so every recipient sees the same thing regardless of their software. For the cleanest pagination, set your print area and page breaks in LibreOffice Calc before uploading, then pick PDF and the Screen or Printer compression preset.
It controls how aggressively embedded images and graphics in the PDF are downsampled, which trades file size against fidelity. Screen (Best) keeps things light for on-screen reading and email; Ebook is a middle ground; Printer and Prepress preserve higher resolution for physical printing at the cost of a larger file; Default is a balanced general-purpose setting. For a sheet that is mostly text and gridlines the difference is small, but it matters once you have embedded charts or images.
No. Both are spreadsheet formats and both are internally ZIP archives of XML, but they are different standards from different origins: ODS is the vendor-neutral OpenDocument format (ISO/IEC 26300) used by LibreOffice and OpenOffice, while XLSX is Microsoft's Office Open XML format. Modern Excel, Google Sheets, and LibreOffice all read and write both, but Microsoft notes some formatting and formula features can shift when a file moves between the two. Converting ODS here produces fixed-layout output (PDF, DOCX, images), not an XLSX — for an editable Excel copy, open the ODS in Excel or Google Sheets and use "Save As → XLSX".
Each sheet in the workbook is rendered in order, so a multi-sheet ODS becomes a multi-page PDF (or one image per sheet), following the print area and page breaks defined in the spreadsheet. For clean pagination, set each sheet's print range and page breaks in LibreOffice Calc before uploading. Very wide sheets may split across pages the same way they would when printed.
Yes. Your ODS is uploaded over an encrypted (TLS) connection, processed on our servers, and deleted automatically after a few hours — there is no sign-up, no watermark, and files are never shared or made public. In our testing, a single-sheet ODS budget with a chart converted to a one-page PDF in a couple of seconds; multi-sheet workbooks render each sheet to its own page in order.
