Should You Manually Convert Currencies or Use Analytics Software?

What can go wrong with manual conversion

Manual conversion usually means exporting Amazon Ads reports into a spreadsheet, layering in an exchange-rate table, and writing formulas to translate spend and sales into a common currency. The main risks are missed currencies, outdated rates, and broken cell references.

• Exchange rates may be applied unevenly if the table is not updated for every reporting period.
• Copying formulas across marketplace tabs can introduce hard-coded values that are hard to detect.
• Small rounding differences compound when reports are combined across many campaigns and accounts.

Where analytics software fits

Dedicated reporting tools are built to handle repeated imports and multi-marketplace consolidation. Instead of maintaining your own currency logic, the software applies consistent conversion rules and flags anomalies in the data. This is especially useful for teams that review Amazon Ads performance weekly or monthly.

For example, a dashboard like Amazon Ads Dashboard by Todoza consolidates spend, sales, ROAS, ACoS, and other metrics from multiple accounts and marketplaces into a single view. That reduces the need to manually reconcile currency columns across separate exports.

When manual conversion still works

Manual conversion can be a reasonable starting point when the reporting scope is small and the exchange-rate source is clear. It may also be enough for a one-off analysis that does not need to be repeated or shared with clients.

• You are only comparing two or three marketplaces with a small number of campaigns.
• The report is needed once, not as a recurring process.
• You have a controlled spreadsheet with validated rates and no team handoff.

Even in these cases, documenting the exact rate and conversion date helps avoid errors later.
