Spreadsheet Speed Improvements

Importing data from common spreadsheet formats is faster and more reliable than ever before. "CSV", "TSV", "XLS" and "XLSX" all have been improved for a seamless and consistent experience working with these data types.

XLS imports are over twice as fast as previous versions.

Taking parts of a file is now more efficient. Import only pulls into memory the requested contents.

CSV import has also dramatically improved for larger files.

The time to access a small part of a CSV file is also much faster.
