A: Thanks for asking. Yes, you can absolutely use OrcaSheets with Excel files on your computer.

OrcaSheets is desktop-first and local-first, so you can load Excel files directly from your machine. If your Excel file has multiple tabs, OrcaSheets can treat each tab as a separate sheet. Similarly, when you load multiple Excel files, each file/sheet can be available for analysis inside OrcaSheets.

You can then cross-reference them, select multiple sheets together, ask questions across them, and use joins where there are common columns such as customer ID, order ID, SKU, date, region, department, etc. OrcaSheets can also create a new joined/combined sheet, which you can then use for further analysis, pivots, dashboards, charts, and AI-assisted workflows.

So yes — multiple Excel files and multiple tabs can be used together.

On languages: OrcaSheets works best today with English for AI prompts and analysis instructions. For data inside files, it can handle normal text data, and we are continuously improving support for multilingual and accented datasets. If you have a specific language in mind, we'd be happy to know and guide you on the best way to try it.

We'd encourage you to test OrcaSheets with a few of your actual Excel files. This kind of multi-file local analysis is one of the main workflows OrcaSheets is built for.
