Using Frontmatter to Optimize Tabular Data Inputs for LLMs
AttemptTwoThousand · reddit · 2026-08-29
Discusses the best format for inputting tabular data to LLMs. The author suggests adopting the Frontmatter concept from static site generators, placing semantic metadata (e.g., country, channel, currency, period) in a YAML block before the CSV table.
Key Points:
- Metadata carries semantics and reduces repetition to save tokens.
- This structure separates global context (metadata) from detailed records (table data).
- Suitable for scenarios like MCP tool responses.
