(Reliability) How much rows/columns can this library handle without crashing?

[Manu-Sakrepatna]

Could you please share the upper limit on number of rows and columns in a sheet and also the number of sheets in an workbook?.. [so that read-excel-file can successfully handle the file]
I am using this library. But want to make sure that to what extent it can handle the rows and column.

I guess no one would be able to tell that.
Other people can report their stats here.
For our project, it's quick for files containing less that 100 rows.
For a file having 2000 rows and 20 columns on a modern mid-tier CPU it parses the file (using a "schema") for 3 seconds (blocking) with 100% single CPU core usage.
So I guess this library really isn't suitable for huge spreadsheets.
I'd use it for files less than 100 rows for optimal performance.
