Report a wrong conversion

If a result looks wrong for a language, send us the language, the exact input, the output you got and the output you expected. Corrections from native speakers are very welcome. A precise example lets us add a regression test so the fix stays in place.

Support for add-ons and the API

Include the product name (for example the Google Sheets add-on or the RapidAPI endpoint), what you were doing, and any error message. Never send passwords, licence secrets or confidential documents.

Business and legal

For licensing, partnerships or legal and privacy requests, use the same address and put the topic in the subject line. Data requests are described in the Privacy Policy.

Before you write

Check the guides, since many questions about “and”, hyphens, billions or cheque wording are answered there.
Read the About page for what the converter does and its limits.
