Good to know
XLSB and legacy XLS lose formulas
Both keep the calculated value and discard the formula behind it. XLSX and ODS keep both. This was found by writing a workbook to every format and reading it back, and the tool warns before it happens.
One sheet or all of them
CSV, TSV, HTML and JSON hold a single sheet. Rather than silently writing the first one, the tool asks which you want and says how many were left out. PDF and the workbook formats keep everything.
UTF-8 is handled properly on the way in
A CSV saved as UTF-8 without a byte order mark, which is what almost every other tool produces, is misread as Latin-1 by the underlying parser and comes back as mojibake. Text files are decoded here before parsing, so accented and non-Latin text survives.
