How can I adjust financials to local currency?

You can easily switch the currency between € and local currency for individual companies:

Please note that the Excel export of a company's financials always reflects the local currency. 

The company database and financial filters are standardized to € for comparability, however you can specify your display currency in your account settings.

Similarly, all chart views in industry reports or on your lists are standardized to € (or your display currency).

When exporting data for multiple companies, e.g. from a list, downloads including "all columns" will provide you with financials in € and local currency.
