Why is my converted XLSX file larger than the original ODF?

File size depends on compression settings and content complexity. Try the Medium quality preset for smaller output, or the file may simply contain data that resists XLSX compression.

What browsers are supported?

Chrome, Firefox, Safari and Edge (all recent versions). Any browser supporting WebAssembly will work.

Is there a watermark on converted XLSX files?

No. Free conversions produce clean output with no watermarks. Your XLSX file is identical to what a paid desktop tool would produce.

Will this converter work on Chromebook?

Yes! Chromebooks run Chrome browser, which fully supports Xonvert's WebAssembly-based conversion engine.

Will I lose quality converting ODF to XLSX?

No — XLSX preserves quality losslessly. Your output will be faithful to the original.

Does this tool support drag and drop?

Absolutely. Drag files directly from your file manager onto the converter area. You can also click to browse, or paste from clipboard.

Can I adjust conversion quality settings?

Yes. The settings panel lets you control output quality, resolution and format-specific parameters. Default settings are optimized for best results.
