Prompt tips
Tiago Cascais outlines a method for using ChatGPT to convert large bodies of text into structured tables for enhanced readability. This approach utilizes specific refinements like concept definitions and external links to improve information density.
Why This Matters
In the technical reality of processing high-volume documentation, standard bullet points often fail to maintain the relationship between complex concepts. Moving from unstructured lists to structured tabular data allows engineers to enforce schema-like consistency on LLM outputs, while automation tools like PowerAutomate bridge the gap between manual prompting and systematic data retrieval.
Key Insights
- Tabular data structures in ChatGPT provide higher signal-to-noise ratios than bullet points for processing large-scale technical texts (2026).
- Concept refinement prompts allow for the inclusion of external metadata, such as Wikipedia links, within the generated output table.
- PowerAutomate can be utilized to interact with browser interfaces to automate repetitive command sequences for LLM interactions.
Practical Applications
- Use Case: Engineers using ChatGPT to generate structured reference tables from technical documentation; Pitfall: Inaccurate link generation if the LLM hallucinating URLs for specific niche concepts.
- Use Case: Automating browser-based LLM workflows via PowerAutomate to process multiple text blocks; Pitfall: UI changes in the browser interface can break automation scripts, requiring frequent maintenance.
