nit: i would move this to the utils folder

[tylermaran]

@ZeeshanZulfiqarAli can you make this optional. with something like a chunk parameter.

I think the response should probably always include the pages, and then have this as an optional output:

inputTokens: 25543,
  outputTokens: 210,
  pages: [],
  chunks: [],

Also if you come up with a better name than chunks I'm game.

const result = await zerox({
  // Required
  filePath: "path/to/file",
  openaiAPIKey: process.env.OPENAI_API_KEY,

  // Optional
  cleanup: true, // Clear images from tmp after run.
  chunk: false, // Return JSON array of elements on each page
});

Why is this doing image>markdown>JSON instead of image>JSON?

[tylermaran]

@batmanscode this is specifically for chunking the OCR results into a JSON array, rather than running JSON extraction.

Primarily for chunking / indexing use cases. We're parsing the Markdown to chunk the page into elements (i.e. h1, table etc.) and returning that as a JSON array.
