Translate a PowerPoint presentation into Spanish

What changes when your slides go into Spanish

Spanish uses the Latin alphabet and reads left to right, so there is no layout rebuild as there would be for Arabic or Chinese. The issues are subtler, and they show on screen.

• Length. Spanish runs noticeably longer than English (it is close to French). Short labels suffer most: Q&A becomes Preguntas y respuestas, Next steps becomes Próximos pasos.
• Inverted marks. Questions and exclamations open with ¿ or ¡: ¿Por qué ahora? In a title that wraps, the opening mark must not be left alone at the end of a line.
• Capitalisation. English Title Case does not carry over. Spanish titles capitalise only the first word and proper nouns: Plan de acción comercial, not Plan De Acción Comercial. Months and days are lower case (marzo, lunes), and capitals keep their accents: ÍNDICE, CONCLUSIÓN.
• Numbers. Spain uses a decimal comma (3,5); Mexico uses a decimal point (3.5). Ordinals are abbreviated 1.º, 2.ª.
• Plurals. Spanish has a separate form for round millions: 1,500 usuarios, but 2,000,000 de usuarios, where a de appears.

Spain or Latin America: register and vocabulary

The same slide reads differently in Madrid and in Mexico City. Three decisions to make before you circulate the deck:

• Vocabulary. ordenador or computadora, móvil or celular, coche or carro. A technical or sales deck usually contains several of these.
• Plural “you”. A closing slide reading “Any questions?” becomes ¿Tenéis preguntas? among colleagues in Spain (vosotros) and ¿Tienen preguntas? in Latin America (ustedes), the latter also being the formal plural in Spain.
• Tú or usted. “Contact us” becomes Contáctanos (tú) or Contáctenos (usted). Informal address is common in Spanish marketing decks, less so in institutional settings or in Latin America. Pick one and keep it consistent across every slide.

To judge the tone before paying, the free sample translates one paragraph of your file at the level you choose: pick a slide that addresses the audience directly. If the deck is for one specific country, have a local reader check the regional terms.

What Manuce delivers, and what it leaves as is

Manuce translates the text on every slide: titles, placeholders, text boxes, shapes, shapes inside groups, and tables. You get your original .pptx back: theme, images, shape positions, animations and transitions stay exactly as they were; only the text changes. A Word version, a PDF and plain text are included too, handy for a Spanish-speaking reviewer who does not have PowerPoint.

What currently stays in the source language:

• speaker notes: if the presenter relies on them, plan to handle them separately;
• charts and SmartArt: an axis labelled Revenue does not become Facturación, and numbers keep their original format;
• slide masters: a Confidential footer set on the master does not become Confidencial;
• text embedded in images.

Two formatting limits matter for Spanish. A paragraph mixing several formats takes on the formatting of its beginning: in “our three priorities”, the bold on tres will be lost, and Spanish word order often shifts anyway. Text box sizes are not recalculated; only the autofit setting already chosen in PowerPoint applies. Manuce does not produce sworn or certified translations either; that rarely matters for a presentation, but it can for an appendix attached to an official file.

Preparing the file before you upload

• Give fixed boxes some room. A title that just fits on one line in English will often wrap in Spanish. Turn on autofit for tight boxes or widen them now, especially buttons and tiles: Learn more becomes Más información.
• Note the master text. Footers, confidentiality notices, department names: list them so you can type the Spanish into the master yourself.
• List chart and SmartArt labels. Axis titles, legends and data labels need redoing by hand; use the opportunity to switch the decimal separator to suit the target country.
• Check your brand font. It must include ñ, á, é, í, ó, ú, ü, ¿ and ¡. Some decorative display fonts lack them, and the character then shows in a different font, which stands out in a heading.
• Simplify mixed-format sentences. A bold or coloured word mid-sentence will be aligned with the start of the paragraph; move it to its own box if the emphasis matters.

Reviewing the Spanish deck before you present

1. Run the file as a slide show, slide by slide: look for overflow, three-line titles and bullets spilling out of their frame.
2. Check every question and exclamation: ¿…? and ¡…! must be complete, with no orphaned opening mark.
3. Check titles: capital on the first word only, months in lower case, accents present on words in capitals.
4. Check dates and numbers: a US-style 03/15 is written 15/03 in Spanish.
5. Fill in what was not translated: charts, SmartArt, masters, images containing text, speaker notes.

The PDF lets you send the deck to a Spanish-speaking reviewer without any risk of the layout being altered.

In practice

1. Prepare the .pptx: widen tight boxes, note master and chart text.
2. Upload the file: an instant quote appears, based on the exact word count.
3. Request the free sample to check the register (tú or usted) before paying.
4. Download the Spanish .pptx, with its Word version, PDF and plain text.
5. Review in slide show mode and complete charts, masters and speaker notes.
