XLSX is a spreadsheet-style table, so it isn't always the format the next tool expects. Converting it to GeoJSON lets you display it on a web map or pass it through a web API without redrawing or re-collecting anything. Because GISConverter runs a full GDAL engine in your browser, the geometry and attributes carry across faithfully, and the file never leaves your device.
Excel (XLSX) (.xlsx): XLSX is the modern Microsoft Excel workbook format. Like CSV it holds tabular data, but with typed cells, multiple sheets and formatting. In a GIS context it is read for its attribute columns, with coordinate columns turning rows into mappable points.
GeoJSON (.geojson): GeoJSON is an open, JSON-based standard (RFC 7946) for encoding vector features and their attributes. It is human-readable, works natively in JavaScript, and is the default vector format of the modern web-mapping stack, so nearly every web map and API speaks it.

No. Your XLSX file is read and converted locally on your device with a GDAL engine compiled to WebAssembly, so it never leaves your computer.
