PPT/Document Automation: Create Professional Presentations in 10 Minutes

Data is the lifeblood of modern enterprises, and Excel is the primary battlefield for data processing. However, the pain point for most professionals with Excel isn't a lack of knowledge, but the vast amount of repetitive operations that consume valuable time—formula writing, data cleaning, report generation, and formatting adjustments. AI is fundamentally changing this, evolving your workflow from "manual operation" to "instruction-driven."

AI + Excel: Say Goodbye to Formula Phobia

Using AI to Generate Excel Formulas

This is one of the most immediately impactful scenarios for AI in office work. You don't need to memorize the syntax of complex formulas like VLOOKUP, INDEX-MATCH, or SUMIFS. Simply describe your needs in natural language, and AI can provide you with the complete formula.

**Meitu AI PPT** and **iFlytek Zhiwen** are viable domestic alternatives, offering better support for Chinese contexts and template styles more aligned with domestic business aesthetics.

Path Two: ChatGPT + Traditional PPT Software

If you require finer control, you can use ChatGPT to generate a PPT outline and copy, then handle the layout in PowerPoint or WPS. Specific steps: 1. Have AI generate a PPT outline based on your topic (titles, key points, speaker notes). 2. Have AI generate refined copy for each slide. 3. Apply a template in your PPT software and fill in the content. 4. Use AI to generate supporting images (e.g., via Midjourney).

Path Three: Microsoft Copilot

If you use Microsoft 365, Copilot can directly generate slides within PowerPoint through conversation. You can say, "Create a 10-page presentation based on this Word document," and it will automatically extract key information and generate the presentation.

AI Document Writing in Practice

Weekly/Monthly Reports

**Prompt Template**: "Based on the following work content, help me write a weekly report. Requirements: Categorized by project, list completed items and next week's plan for each project, with a professional but not overly formal tone. Work content: [Paste your work log]."

It's recommended to develop the habit of recording your daily work in one or two sentences. Feed these records to AI on Friday, and you can generate a well-structured weekly report in minutes.

Meeting Minutes

Feishu and Tencent Meeting already have built-in AI transcription features that can automatically generate meeting minutes. If your meeting tool lacks this function, you can use a speech-to-text tool (like iFlytek Tingjian or Qwen Tingwu) to get a transcript, then have AI organize it into structured minutes: "Please organize the following meeting transcript, extracting: 1. Discussion topics 2. Key decisions 3. Action items and responsible persons 4. Next meeting arrangements."

Proposals/Plans

AI is particularly adept at generating the framework and first draft of proposals. You provide the core information (objectives, background, budget, timeline), and AI helps organize it into a complete proposal document. Your job is to verify data accuracy, supplement professional judgment, and adjust the tone and style.

Quantitative Reference for Efficiency Gains

According to McKinsey research, AI office tools can help knowledge workers save approximately 60-70% of the time spent on information gathering and first-draft generation. This doesn't mean your workload is reduced by 70%—rather, you can reinvest the saved time into more valuable thinking, decision-making, and communication.

The ultimate goal is not "to have AI do everything," but "to use AI for mechanical tasks, allowing you to focus on creative and judgmental work." While your colleagues are still manually adjusting formats, you're already contemplating the core strategy of the proposal—this is the competitive advantage brought by AI-powered office work.

Congratulations on completing the free chapter on AI-assisted office work! The full course will delve deeper into email automation, knowledge base management, meeting efficiency enhancement, and team collaboration AI tools.

In 2024, the release of Sora made the world realize that AI video has evolved from an "interesting experiment" to a "usable tool." In 2025-2026, AI video tools are advancing at an unprecedented pace, embraced by everyone from hobbyists to professional filmmakers.

Four Major Categories of AI Video Tools

1. AI Editing Tools

These tools help you complete traditional editing tasks faster: automatic cutting, subtitle generation, color grading, audio optimization. Representative tools: **Jianying** (most mainstream in China, by ByteDance), **CapCut** (international version of Jianying), **Descript** (pioneer in text-based video editing).

Suitable for: Short video creation, Vlog editing, meeting recording organization, training video production. Lowest entry barrier, usable on a mobile phone.

2. AI Video Generation Tools

Input text or images, and AI directly generates video clips. Representative tools: **Runway Gen-3** (most stable quality for commercial use), **Pika** (stylized video generation), **Sora** (OpenAI's video generator), **Kuaishou Keling** (available in China, by Kuaishou), **Vidu** (available in China, by Shengshu Technology).

Suitable for: Advertising creativity, concept showcases, social media content, film previews. Generated clips are typically 5-15 seconds, with quality rapidly improving.

3. AI Digital Human Tools

Generate virtual hosts or digital avatars to appear on screen for you. Representative tools: **HeyGen** (most mature commercial digital human platform), **D-ID**, **Guiji Zhineng** (domestic solution).

Suitable for: Product introduction videos, training courses, multilingual localization. Eliminates the need for real actors, lighting, cameras, and makeup, significantly lowering the barrier to video production.

4. AI-Assisted Tools

Tools providing specific capabilities within the video production workflow: **Topaz Video AI** (video enhancement/super-resolution), **Elevenlabs** (AI voiceover/voice cloning), **Opus Clip** (automatically cuts long videos into short clips).

Capability Boundaries of Various Tools

Current limitations of AI video tools are real: generated video length is restricted (typically 5-15 seconds), character movements may be unnatural, hand details are often flawed, and physical laws in complex scenes may be inaccurate. Understanding these boundaries is crucial, as it determines how you can reasonably use AI in practical work.

A practical principle: **AI generates material clips, humans assemble and edit.** Don't expect AI to generate a perfect long video in one go. Instead, use it to generate a large number of creative clips, and you select, arrange, and adjust them.

Industry Trends

Content competition on short video platforms (Douyin, Kuaishou, Xiaohongshu) is intensifying. AI tools enable small teams or even individuals to produce professional-level content. It is estimated that by 2027, over 50% of short video content will be produced with the assistance of AI tools. Creators who master these tools early will have a significant efficiency advantage.

Having understood the landscape of AI video tools, the next chapter will focus on the most practical AI features of Jianying, guiding you from zero to creating a professional short video.
