To create a clean template to start creating a new "To USD" data page, use the old data page and run the following regular expression replacement in Writer (make sure the "regular expression" checkbox is checked):
search expression: =\{\{#expr:\(\{\{\{1\}\}\}/ *([0-9])*(\.)?([0-9])* *\)round\{\{#ifeq:\{\{\{round\}\}\}
replace expression: ={{#expr:({{{1}}}/ xxxxxxxxxxx )round{{#ifeq:{{{round}}}
Last time it ran with 189 replacements for "To USD" and 188 replacements for "International dollars". The data for Spain in "International dollars" had a typo (2 decimal points), so the regular expression didn't match that one.
