CSV is a natively supported file format, you can use it without an additional installation. Just upload it to your projects and start the localization.

Files uploaded via alignment automatically add labels to the context when sent for alignment. This improves translation matching accuracy when importing files into Crowdin. However, labels and context do not affect the export process.

For files without a defined structure, translation uploads are handled by an experimental machine learning technology.
