Selecting what to parse

By default LlamaParse will extract all the visible content of every page of a document



Parsing only some pages

Section titled “Parsing only some pages”

You can specify the pages you want to parse by passing specific page numbers as a comma-separated list in the target_pages argument. Pages are numbered starting at 0.

parser = LlamaParse(
  target_pages="0,1,2,22,33"
)

The range syntax is also supported target_pages=0-2,6-22,33.



Parsing only a targeted area of a document

Section titled “Parsing only a targeted area of a document”

You can specify an area of a document that you want to parse. This can be helpful to remove headers and footers.

To do so you need to provide the bounding box margin expressed as a ratio compare to the page size between 0 and 1 in bbox_left, bbox_right, bbox_top and bbox_bottom.

Examples:

  • To not parse the top 10% of a document: bbox_top=0.1
  • To not parse the top 10% and bottom 20% of a document: bbbox_top=0.1 and bbox_bottom=0.2,
parser = LlamaParse(
  bbox_left=0.2
)

Bounding box (legacy)

Section titled “Bounding box (legacy)”

We support a deprecated way of doing so where it is possible to provide the bounding box margin in clockwise order from the top in a comma separated string in the bounding_box arguments. The margins are expressed as a ratio compare to the page size between 0 and 1.

Examples:

  • To not parse the top 10% of a document: bounding_box="0.1,0,0,0"
  • To not parse the top 10% and bottom 20% of a document: bounding_box="0.1,0,0.2,0"
parser = LlamaParse(
  bounding_box="0.1,0.4,0.2,0.3"
)

Limiting number of page to parse

Section titled “Limiting number of page to parse”

If you want to limit the maximum amount of pages to parse you can use the parameter max_pages. LlamaParse will stop parsing the document after the specified pages.

parser = LlamaParse(
  max_pages=25
)
