FAQ

Questions arquero owners ask.

  • 01

    What is the maximum CSV size supported?

    The engine runs locally via Node.js, meaning it can handle gigabytes of CSV data as long as your machine has sufficient RAM. There is no artificial size cap.

  • 02

    Which aggregation functions are supported?

    Currently: sum, mean, count, min, and max. You can map different columns to different aggregations in a single call (e.g., sum Revenue and count Orders simultaneously).

  • 03

    Why use Arquero instead of sending the CSV to the AI?

    LLMs charge per token. A large CSV can cost dollars per query and the math will be hallucinated. Arquero is free, local, and processes data with mathematically perfect deterministic precision.
