Extracting Tables

pdfplumber.core exposes two table entry points:

(pdf/extract-table doc opts)
(pdf/extract-tables doc opts)

Both also accept a cropped page view from crop-page. extract-table returns one table map. extract-tables returns a vector and currently returns at most one table.

Return Shape

Tables have this shape:

{:page-number 1
 :strategy :lines
 :bbox [72.0 92.0 540.0 152.0]
 :rows [[{:text "Date" :bbox [72.0 92.0 300.0 122.0]}
         {:text "Amount" :bbox [300.0 92.0 540.0 122.0]}]
        [{:text "2026-01-01" :bbox [72.0 122.0 300.0 152.0]}
         {:text "$10.00" :bbox [300.0 122.0 540.0 152.0]}]]
 :cells [[72.0 92.0 300.0 122.0]
         [300.0 92.0 540.0 122.0]
         [72.0 122.0 300.0 152.0]
         [300.0 122.0 540.0 152.0]]
 :debug {:horizontal-lines 3
         :vertical-lines 3
         :cells 4}}

:rows is the main result: a vector of rows, each a vector of cell maps. Each cell has :text and :bbox.

The exact coordinates above are illustrative. The shape matches the API.

Options

Shared options:

• :page - 1-based page number.
• :bbox - restrict extraction to [x0 top x1 bottom].
• :strategy - :lines by default, or :text.

:lines option:

• :snap-tolerance - default 3.0. Near-collinear ruling positions within this tolerance are snapped together.

:text options:

• :text-x-tolerance - default 3.0. Groups similar word left edges into inferred columns.
• :text-y-tolerance - default 3.0. Groups words into rows.
• :min-words-vertical - default 3. Minimum words required to support an inferred column left edge.
• :min-words-horizontal - default 1. Minimum non-blank cells required to keep a row.

Table extraction also passes options through to word/object extraction. That means :page, :bbox, :x-tolerance, :y-tolerance, and :types can affect the data the table strategies see. In normal use, prefer the table-specific options above plus :page and :bbox.

Lines Strategy

Use :lines for ruled tables: tables with drawn horizontal and vertical lines, including rectangle edges.

(pdf/with-pdf [doc "invoice.pdf"]
  (pdf/extract-table doc {:page 1 :strategy :lines}))

The implementation:

• extracts graphical objects from the page
• uses horizontal and vertical :line objects plus :rect sides as table edges
• snaps nearby x/y positions using :snap-tolerance
• finds grid cells whose four corners are intersections
• assigns words to cells by word-center containment

The returned table includes :cells for the grid cell bounding boxes and :debug counts for :horizontal-lines, :vertical-lines, and :cells.

Text Strategy

Use :text for whitespace-aligned tables without ruling lines.

(pdf/with-pdf [doc "statement.pdf"]
  (pdf/extract-table doc {:page 1
                          :strategy :text
                          :text-x-tolerance 3.0
                          :text-y-tolerance 3.0}))

The implementation:

• extracts words
• groups words into rows by :top within :text-y-tolerance
• infers column left edges from repeated word :x0 positions within :text-x-tolerance
• keeps column edges supported by at least :min-words-vertical words
• filters rows by :min-words-horizontal

The returned table includes :rows, :bbox, and :debug with :rows and :columns. It does not include :cells because cells are inferred from text bands rather than a ruled grid.

Cropping Before Extraction

Use crop-page to isolate the region that contains the table. A cropped page view carries the original document handle plus :page and :bbox; extraction functions accept it in place of a document.

(pdf/with-pdf [doc "statement.pdf"]
  (let [table-region (pdf/crop-page doc {:page 1
                                         :bbox [40.0 250.0 560.0 520.0]})]
    (pdf/extract-table table-region {:strategy :lines})))

Explicit options override the view:

(pdf/extract-table table-region {:page 2 :strategy :text})

Cropping filters extraction to the view's bounding box. Coordinates in returned rows, cells, words, and objects remain in the original page coordinate system.
