# Local Files

Phiona supports multiple different data types that may be local to your computer. We currently support the following:

* XLS / XLSX (Excel) files
* CSV files
* TXT files
* Unstructured data formats like XML and JSON
* Apache Parquet files

Some file formats are a bit tricky to parse- please try to strip your datasets of any unnecessary headers or footers before uploading. If you're still having issues, feel free to reach out to us at [support@phiona.com](mailto:%20support@phiona.com).
