Multiple hexadecimal -> base32 string converter
This form converts list of hex strings (one string per line, can be exported from Libre/OpenOffice Calc as CSV file from sheet with single columm or just by selection)
to list of base32 strings.
Each output line contains base32 string (if conversion succeded) and optional comment after comma if conversion failed (uneven number of hex characters). This can be treated as CSV file with two columns and imported back to Calc ("Paste Special" option and marking comma as separator in text import dialog works too).
