Frequently Asked Questions

What is a CSV file?

CSV (Comma-Separated Values) is a plain text format that stores data in rows and columns. It’s widely used for localization because it’s simple, portable, and easy to work with across tools, frameworks, and e-commerce platforms.

How do I translate CSV files?

Upload your CSV file and add a short description of your product. PTC will use that context to generate accurate translations into your chosen languages. Once translation is done, head to the Translations tab to review individual strings, then download your translated files as a ZIP from the Resource files tab. For a full over view, see the getting started guide.

What types of CSV files does PTC support?

PTC supports UTF-8 encoded CSV files with a key column and one or more content columns. That covers most CSV localization workflows used in apps, SaaS products, and e-commerce systems like Shopify or Magento.

Is PTC good for e-commerce CSV translation?

Yes. PTC works well for Shopify, Magento, and similar platforms. You can translate product titles, descriptions, and other strings in bulk, with the same context-aware AI that keeps terminology consistent across your store.
PTC also includes Paste to Translate for content that does not live in your CSV, like app store listings, help center articles, onboarding emails, and support content. Since it uses the same project context, terminology stays consistent across everything you ship.

Will my CSV delimiters stay intact?

Yes. PTC keeps your original CSV structure intact, including delimiters, column order, placeholders, and formatting, so your translated file is ready to import.

Does PTC support UTF-8 encoding?

Yes. PTC supports UTF-8 encoded CSV files, which allows translated content to display correctly across accented characters and non-Latin scripts like Arabic, Japanese, and Chinese.

Can PTC handle large CSV files?

Yes. Large files can be uploaded in the app or sent through the API for automated translation at scale.
