Convert ODT to XLSX
Updated Jul 2026
ODT is the document format used by free office suites, and XLSX is the spreadsheet format Excel and Google Sheets read. To convert, open the file in a converter and export it as XLSX, which places any tables or lists from the document into spreadsheet cells. Doing this on your own computer means the file never leaves your machine.

ODT vs XLSX: what actually changes
| ODT | XLSX | |
|---|---|---|
| What it holds | Free-flowing text, paragraphs, and images | Rows and columns of cells |
| Formulas and calculations | No | Yes, built in |
| Keeps page layout and formatting | Yes, fonts, headings, and styles stay intact | No, content is reduced to plain cell values |
| Opens in | a free office suite, Word | Excel, Google Sheets, Numbers |
| Best suited for | Letters, reports, essays | Lists, budgets, and data you want to sort or total |
| File size | Compact | Similar, sometimes a little larger once content sits in a grid |
When to convert, and when not to
Convert ODT to XLSX when the document is really a table underneath, like a budget, inventory, or list, and you want to sort, filter, or run calculations on it in a spreadsheet.
Keep the ODT if it's a written document like a letter, report, or essay, since converting to XLSX strips out paragraphs, headings, and page formatting and leaves only raw cell values.
Why not just use an online converter?
ODT documents often hold personal detail, from letters and financial notes to draft reports. Uploading one to an online converter to get an XLSX back means that content sits on someone else's server while it's processed. Converting on your own computer keeps the document, and whatever's written in it, on your machine the whole time.
Questions
Will converting ODT to XLSX lose any formatting?
Yes, mostly. XLSX stores content in cells, so paragraph formatting, headings, and page layout from the ODT don't carry over. Tables and lists translate reasonably well since they already have a row-and-column shape.
Does ODT to XLSX keep tables intact?
Tables generally come across well, since a table in a document already maps to rows and columns. Plain paragraphs of text usually end up as one cell per paragraph, which isn't very useful in a spreadsheet.
Can I still open the file in a free office suite after converting?
Yes. The new XLSX file opens fine in free spreadsheet apps, a free office suite Calc, Excel, or Google Sheets, since XLSX is a standard spreadsheet format all of them read.
Does the conversion add or remove any data?
No new data is invented and none is silently dropped, but a text document does get restructured into a spreadsheet's cell-based layout, so it looks different from the original.
Can I convert ODT to XLSX without uploading the file anywhere?
Yes. Morphjet converts the file locally on your Mac or Windows PC, so nothing is sent over the internet, even with your wifi off.
