FAQ
Questions Output Format Token Comparator owners ask.
- 01
How do I compare token usage between JSON and YAML?
You can use the calculate_format_metrics capability. Provide your data structure and include both "JSON" and "YAML" in the output formats list to see the exact token counts and the compression ratio.
- 02
What is the nesting penalty?
The nesting penalty refers to how much extra token overhead is added as data structures become more deeply nested. You can measure this specifically using the analyze_nesting_impact capability.
- 03
Can I estimate the cost of converting data from XML to CSV?
Yes, use the estimate_conversion_cost capability. It will calculate the estimated token delta and the difficulty of the conversion based on the parsing complexity of the formats.
