Problem
The confluence content is old and still contains old style content. In Confluence it looks like that (TaxInfo example):

This will import into Phonemos as plain text instead of the expected table.
Solution
Convert the Confluence content using the method described in https://confluence.atlassian.com/conf81/migration-from-wiki-markup-to-xhtml-based-storage-format-1209876102.html:
goto https://<confluence-root>/admin/unmigratedcontent.action
start the conversion
→ Content that is not converted probably still still contains unknown macros
Additional Considerations
If you have custom tags around the markdown (as {web08-table} in the example above you have to replace that first. If you have some pages it’s best to do this directly on the database:
1
2
3
UPDATE bodycontent
SET body = regexp_replace(body, E'\\{web08-table[^\\}]*\\}', '', 'g')
WHERE body LIKE '%web08-table%';or to convert link style macros
1
2
3
UPDATE bodycontent
SET body = regexp_replace(body, E'\\{web08-link:([^\\}]*)\\}', E'[\\1]', 'g')
WHERE body LIKE '%{web08-link%';after that clear the cache (important, /admin/cache/showStatistics.action) run the converter again.
