What are the 6.x Calc Import/Export Filters?

On 19 Nov 2015 I detailed the LO-5.0.0 Calc import/export filters. 5 years later, what are the current Calc filters?

LO-5.x Calc filters

LO-6.x Base filters
LO-6.x Draw filters
LO-6.x Graphics filters
LO-6.x Impress filters
LO-6.x Math filters
LO-6.x Writer filters

calc-6.ods
calc-6.odt
calc-6.txt.odt (actually is .txt (TXT files not allowed on upload))

LO-6.4 file-conversion filters
(many thanks to Mike Kaganski for the last link; he says that the filters began to be documented at v6.3)

~$ lsb_release -a Devuan GNU/Linux 3 (beowulf)
~$ soffice.bin --version LibreOffice 6.1.5.2 10(Build:2)

Hand-extracted from /usr/lib/libreoffice/share/registry/calc.xcd

Mostly the same as the 40 Calc filters in LO-5; some added, some removed + some small alterations.
