Is it possible to convert Excel spreadsheets into MediaWiki markup? I stumpled upon strange recommendations exporting to HTML and convert it into markup. Is there a solution, ma
You can do this in a graphical interface, with proper software.
{|
with {| class="wikitable"
to have pretty backgrounds and borders.LibreOffice is free/open source software and is better than Excel at handling Excel's own spreadsheets, as you see. There used to be an Office plugin too but I've not heard of anyone using it recently.
You may need table styles, available in LibreOffice 5+; but in the meanwhile you can just apply CSS classes to your MediaWiki table.
Alternatively, just copy and paste your table in a page powered by VisualEditor, which is quite good for tables. If your wiki doens't have it, you could still use the MediaWiki.org sandbox: paste your rich text, click the pencil button at the top and then "wikitext/source editing", cut the wikitext and paste into your wiki.
