You can use files in Amazon S3 or on your local (on-premises) network as data sources. QuickSight supports files in the following formats:
CSV and TSV – Comma-delimited and tab-delimited text files
ELF and CLF – Extended and common log format files
JSON – Flat or semistructured data files
XLSX – Microsoft Excel files
QuickSight supports UTF-8 file encoding, but not UTF-8 (with BOM).
Files in Amazon S3 that have been compressed with zip, or gzip (www.gzip.org), can be imported as-is. If you used another compression program for files in Amazon S3, or if the files are on your local network, remove compression before importing them.
For additional information on supported data sources, see this guide.
Thank you, Peter. Support of XML files in Quicksight was a bad assumption on my part. They are so prevalent where I work that I assumed they were supported everywhere.
