 Excel is extremely aggressive in reading files. Adding the XLS extension to any
-text file (where the only characters are ANSI display chars) tricks Excel into
-processing the file as if it were a CSV or TSV file, even if the result is not
-useful!  This library attempts to replicate that behavior.
+file tricks Excel into processing the file.
 
-The best approach is to validate the desired worksheet and ensure it has the
-expected number of rows or columns.  Extracting the range is extremely simple:
+If the file matches certain heuristics, Excel will use a format-specific parser.
 
-```js
-var range = XLSX.utils.decode_range(worksheet['!ref']);
-var ncols = range.e.c - range.s.c + 1, nrows = range.e.r - range.s.r + 1;
-```
+If it cannot deduce the file type, Excel will parse the unknown file as if it
+were CSV or TSV. SheetJS attempts to replicate that behavior.
