OCR Extract Table

OCR Extract Table

Type: ocr-extract-table · Package: OCR Activities v1.0.0 · Output: DataTable

Detects a table within an image, grouping the recognized words into rows and columns based on their position, and returns it as a DataTable. Useful for extracting a tabular list from a scanned document (an invoice detail, a data table).

How it works

Run OCR on the image and, based on the coordinates of each word, reconstruct the structure of the table. By default it treats the first row as headers (hasHeader) and discards rows with fewer cells than minColumns (to ignore loose text that is not part of the table).

Required parameters

Parameter	Editor	Description
`path`	expression	Image file path.

Optional parameters

Parameter	Editor	Description
`language`	expression	Language code: `eng` (def.) · `spa` · `eng+spa`.
`preprocess`	expression	Limpieza previa: `none` · `auto` (def.) · `deskew` · `binarize`.
`hasHeader`	boolean	Treat the first row as column names. By default `true`.
`minColumns`	expression	Discard rows with fewer cells than this number. By default `2`.

Output

Returns a DataTable with the detected rows and columns.

Example

OCR Extract Table   path = = rutaEscaneo   language = "spa"   → output: tabla
For Each   items = = tabla   itemVariable = fila
 └─ activities:
      Log   message = = str(row["Description"]) + " — " + str(row["Value"])
