--- title: "User guide" manual: "AI Localization" version: "main" permalink: "https://docs.typo3.org/permalink/nitsan/ns-t3al:user-guide@main" source: "UserGuide/Index.rst" rendered: "2026-10-20T11:46:30+00:00" --- # User guide {#user-guide} Open **Admin Tools > AI Localization** (on TYPO3 v14: **Administration > AI Localization**). The module has three tabs, **Translate**, **Search** and **Logs**, and a **Guide** button on the right. - [Select extension, file and languages](https://docs.typo3.org/permalink/nitsan/ns-t3al:select-extension-file-and-languages@main) - [Edit labels in the grid](https://docs.typo3.org/permalink/nitsan/ns-t3al:edit-labels-in-the-grid@main) - [Translate with AI](https://docs.typo3.org/permalink/nitsan/ns-t3al:translate-with-ai@main) - [Save](https://docs.typo3.org/permalink/nitsan/ns-t3al:save@main) - [Create a language file](https://docs.typo3.org/permalink/nitsan/ns-t3al:create-a-language-file@main) - [CSV export and import](https://docs.typo3.org/permalink/nitsan/ns-t3al:csv-export-and-import@main) - [Export ZIP](https://docs.typo3.org/permalink/nitsan/ns-t3al:export-zip@main) - [Search](https://docs.typo3.org/permalink/nitsan/ns-t3al:search@main) - [Logs](https://docs.typo3.org/permalink/nitsan/ns-t3al:logs@main) - [Interactive guide](https://docs.typo3.org/permalink/nitsan/ns-t3al:interactive-guide@main) ## Select extension, file and languages {#user-guide-select} ![Filter with extension type, extension, language file, new language file and target languages](../Images/filter.png) - **Extension type** **Local** (your own and third-party extensions, default), **System** (TYPO3 system extensions) or **All**. - **Extension** Type to search by title or extension key. - **Language file** The `.xlf` files directly in `Resources/Private/Language/` of the extension. Files in subfolders and translation-only files are not listed. - **Target languages** Search and pick one or more languages. Each language becomes a column in the grid. English is always the source (`default`) column. ## Edit labels in the grid {#user-guide-grid} The grid shows one row per label key. You can type in every cell you are allowed to edit. - Empty translations and missing English sources are highlighted, and translations identical to the English text are marked. - Administrators can rename keys, add a row below (**+**), delete a row and drag rows to a new position. - **Sort by key** sorts the rows alphabetically; the order is written on the next save. - While there are unsaved changes, the **Save** button is highlighted and TYPO3 asks before you leave the module. ## Translate with AI {#user-guide-translate} ![AI provider selection and editor actions Translate, Save, Reload, Export CSV and Export ZIP](../Images/editor-card.png) 1. Under **AI provider**, choose **OpenAI**, **Gemini**, **DeepL** or **Google Translate**. For OpenAI and Gemini you can also pick the model. 1. Click **Translate**. 1. The empty translations of all selected languages are filled. Existing translations are not changed. 1. Review the result in the grid and correct it if needed. If every label already has a translation, the module shows **Nothing to translate** and nothing changes. If some labels could not be translated, a warning tells you how many were filled; the rest stay empty. ## Save {#user-guide-save} Click **Save** (disk icon) to write the grid to the language files. - Translations are written to `..xlf` next to the English file, for example `de.locallang.xlf`. - Only files that really changed are written. If nothing changed, you see **No changes**. - For TYPO3 system extensions the English file is read-only and the translations are saved in the TYPO3 labels folder (`var/labels///` in Composer mode). ![Translation Success message after saving](../Images/save-success.png) **Reload** discards unsaved changes and reloads the files from disk. ## Create a language file {#user-guide-create-file} Administrators can enter a file name in **New language file**, for example `locallang_db.xlf`, and click **Create file**. An empty XLIFF file is created and selected. Creating files is not possible for TYPO3 system extensions. ## CSV export and import {#user-guide-csv} - **Export CSV** Downloads the current grid as a CSV file (key, English and one column per language), for example to send it to a translator. - **Import CSV** Administrators choose a CSV file and click **Import CSV**. The CSV is merged into the grid: existing labels are updated, new keys are added, and keys or languages that are not in the CSV stay unchanged. Click **Save** to write the result. A header `en`, `default` or `… (default)` marks the English column. ## Export ZIP {#user-guide-zip} **Export ZIP** downloads all language files of the extension as a ZIP archive. It is available when [enableExport](https://docs.typo3.org/permalink/nitsan/ns-t3al:confval-confval-enableexport@main) is enabled and the extension is not a TYPO3 system extension. ## Search {#user-guide-search} ![Search tab with results in the ns_license language files](../Images/search.png) Enter a text, optionally choose a language (**All languages**, **English (source)** or one language) and click **Search all**. The search is case-insensitive. Click a result to open the file in the Translate tab. At most 100 files are listed; refine the text or pick a language if there are more. ## Logs {#user-guide-logs} ![Translation Logs with a saved German translation and its diff](../Images/logs.png) On the **Logs** tab choose an extension, then filter by language file and target language. Each entry shows the date and the removed and added text per label. **Toggle Collapse** expands or collapses all entries, and the delete icon removes an entry. Logs are only written when [enableLogs](https://docs.typo3.org/permalink/nitsan/ns-t3al:confval-confval-enablelogs@main) is enabled; old entries are removed after [logRetentionDays](https://docs.typo3.org/permalink/nitsan/ns-t3al:confval-confval-logretentiondays@main). ## Interactive guide {#user-guide-guide} Click **Guide** at the top right to open an interactive walkthrough of the module in a modal window.
