Translate PPTX

Translate PPTX

Use the slideforge MCP server to translate an existing PowerPoint deck without re-creating it from scratch. Every shape, chart, table, and embedded image stays exactly where it was — only the text content changes.

When to trigger

Any request to translate, localize, or change the language of a PowerPoint file. Examples:

• "Translate this deck to German"
• "Can you localize this presentation into Spanish?"
• "Convert my PPTX from English to French"

Tools used

• translate_deck — main tool
• upload_asset with purpose=translate — if the user uploads a file rather than passing a URL or job_id

Workflow

If the user has a prior slideforge job (preferred)

{
  "target_language": "de",
  "job_id": "<previous slide or deck job_id>"
}

No file transfer needed — fastest path.

If the user pastes a public URL to a PPTX

{
  "target_language": "de",
  "pptx_url": "https://example.com/deck.pptx"
}

If the user uploads a file

First upload via upload_asset:

{
  "purpose": "translate",
  "data": "<base64-encoded .pptx>",
  "filename": "my-deck.pptx",
  "target_language": "de"
}

Returns a job_id; poll or set include_preview to get the result inline.

Supported languages

32 languages, grouped by script family. source_language is auto-detected by default; override if needed. No CJK or RTL scripts yet.

Full names: English, German, French, Spanish, Italian, Portuguese, Dutch, Swedish, Danish, Norwegian, Finnish, Icelandic, Polish, Czech, Slovak, Hungarian, Romanian, Croatian, Slovenian, Estonian, Lithuanian, Latvian, Russian, Ukrainian, Bulgarian, Serbian, Turkish, Catalan, Galician, Indonesian, Vietnamese, Greek.

Useful options

• include_notes: true — translate speaker notes (default false)
• include_tables: true — translate table cells (default true)
• concise_mode: true — prefer shorter translations when text boxes are tight (e.g., German is ~30% longer than English; enable to keep layouts clean)

Pricing

$0.02 per slide. A 20-slide deck = $0.40. 100-slide deck = $2.00.

Delivery

Download the file via header-auth: GET /v1/jobs/<job_id>/pptx with Authorization: Bearer sf_live_YOUR_KEY (ownership-checked). To hand off a shareable link instead, POST /v1/jobs/<job_id>/download-url mints a short-TTL, single-use, revocable one. The file is a real, editable .pptx — every translated element stays as a native PowerPoint shape.

Anti-patterns

• Don't re-generate the deck from scratch — that loses formatting and costs 10x more. Use translate_deck on the existing file.
• Don't translate deck-by-deck in a loop if the user has 10 decks. Mention that the REST API supports batch calls for automation.
• Don't translate placeholder text like {{company_name}} — flag these to the user before translating; they usually should stay as-is.
