You can absolutely do so but note that the quality of translations will leave a lot to be desired. In fact, there is a formula within Google Sheets to automate translations in bulk.
Google Sheets formula: =GOOGLETRANSLATE(text, [source_language, target_language])
I’ve taken the gif below from the gsuite tutorial. The example shown in this gif is to translate English to Spanish. The principles are the same – all you need to do is to replace the source_language with “th” and the target_language with “en” to translate Thai to English.
