To use with LO-Writer: - open the html-file directly with LO-Writer

To use with LO-Calc: - create new LO-Calc doc - menu: "Sheet/Link to External Data" and select the generated html file

There are 5 options for the generated html: - values without any formatting or comments - values with formatting & comments (default) - formulas with formatting & comments - extra table for comments, i.e. units, formulas & alias (default without) - with/without table borders (default with) The options are set in the macrofile, not via gui.

Imports to Calc does not respect column width & row heigth, html in browser and Writer does... Same goes for merged cells. Neither Writer nor Calc parses the comments, hence the option for extra table.

Alias: The extra table helps in recreating alias in Calc, to redefine the name within Calc (look in LO-Calc docs if you want to know how).

Obviously the use of alias is only working for an alias that has references that Calc understands, so "=A1+B2" works, while "=Box.Length" does not. For the cases where the evaluation should work, one still has to select the cell with the formula and click the "equal sign" in  the formula bar of Calc user interface.

Comments contains the following as per availability: - unit strings when defined on cells in fc - name of alias when defined on cells in fc  - formulas if the option to evaluate expressions to values is True (default) - evaluated value if the option to keep formulas is True

For the option "paste values" it is just the evaluated values of the cells. The option does not pass along comments. """
