Frequently asked questions

What is ODS to XLSX?

Convert a LibreOffice Calc .ods sheet to Excel .xlsx without installing anything.

When would I actually use this?

Getting a table out of a workbook and into something else — JSON for an API, CSV for an import, HTML for a page — opening a file whose software you do not have, and cleaning a sheet before you hand it on.

What is the most common mistake?

Expecting the formula to survive the trip. A converted file carries the last value the spreadsheet computed, not the calculation behind it — and a workbook written by a program can carry the formula with no cached value at all, which most readers discard along with the cell.

How is ODS to XLSX different from XLSX to ODS?

They sit next to each other but answer different questions. XLSX to ODS: convert an Excel workbook to OpenDocument .ods for LibreOffice Calc. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Numbers to XLSX is the closest one after this: Open an Apple Numbers file and save it as Excel .xlsx — no Mac required.

What else is worth having open alongside it?

XLS to XLSX and XLSB to XLSX — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

Nothing leaves the browser. An .xlsx and an .ods are both zipped XML, read here against their published specifications. Dates are the fragile part — a spreadsheet date is a number counted from an epoch the workbook itself declares, so the same 45000 is two different days depending on a flag most files never show you.

ComparisonXLS, XLSX, XLSM and XLSB: Which Is Which, and Which You WantFour extensions, three of them the same box with different lids. Rename an XLSX to .zip and it opens — that single fact explains the whole family, and explains why XLS, which does not, is the one still causing trouble.ExplainerThe .ods File That Is Valid, and That Your Reader RefusesOpenDocument makes styles.xml optional. Several readers demand it and reject the whole document without it — "Cannot find file styles.xml in zip" on a file that is not broken.ExplainerThe Workbook with Twenty-Three Formulas That Reported NoneA cell can hold a formula and no cached result. A reader that skips empty cells throws the formula away with them — and says the file has none. One parsing option separates the two cases.ExplainerWhy Your CSV Breaks Accents and Dates in ExcelThree completely different faults hide behind the same sentence. One is the encoding, one is the separator, one is Excel guessing at types while it opens the file — and the fix for each is different. Here is how to tell them apart in five seconds.ExplainerConverting Formulas to Values Keeps the Cached Answer, Not the CalculationA spreadsheet file stores both the formula and the last answer Excel computed. Stripping the formula leaves the stored answer — and leaves a blank wherever the file never carried one.How-toOne File per Tab, and What a Split Leaves BehindSplitting a workbook writes one .xlsx per sheet, named after the tab. It carries the values across and not the formulas — which is the right default when the point is to send one department its own tab.
