What method should a System Administrator use to convert standard country fields to ISO codes in existing Accounts?

To effectively convert standard country fields to ISO codes in existing Accounts, using the Mass Update Addresses feature is beneficial. This method allows the System Administrator to modify a large number of records simultaneously, ensuring consistency and efficiency in the update process.

Mass Update Addresses specifically targets location-related fields, such as country names, allowing for the conversion of these fields to standardized formats, like ISO codes. This is particularly useful in scenarios where data uniformity is crucial for reporting or integration with other systems that require a specific format.

In contrast, other methods like List View Inline Editing or Data.com Clean might not provide the same level of bulk modification capability for this specific purpose, while Report Exports generally serve to extract data rather than modify it. Thus, the choice of Mass Update Addresses aligns perfectly with the requirement to systematically convert country fields into their ISO code equivalents.
