Usage from within Python:
```
  from xlsx2csv import Xlsx2csv

# Recommended: using context manager for proper resource cleanup
  with Xlsx2csv("myfile.xlsx", outputencoding="utf-8") as xlsx2csv:
      xlsx2csv.convert("myfile.csv")

# Simple usage (but may cause ResourceWarning in modern Python)
  Xlsx2csv("myfile.xlsx", outputencoding="utf-8").convert("myfile.csv")
```

Expat SAX parser is used for XML parsing.
