How Can KlearStack OCR Extract Specific Data like Tables and Line Items?

Image Analysis

When you upload an image containing tables or line items, KlearStack’s OCR engine performs a detailed image analysis. It identifies the presence of structured data, such as tables or lists within the image.

Layout Recognition

KlearStack recognizes the layout and structure of tables and line items in the image. It identifies rows, columns, and cell boundaries, understanding the data’s organization.

Character Recognition

Characters within each cell of the table or line item list is recognized. The tool reads the text within these cells, character by character.

Data Extraction

As the characters are recognized, KlearStack aggregates them into meaningful data. 

  • For tables, it assembles the data into rows and columns, maintaining the structure of the original table. 
  • For line items, it creates a structured list of items with associated details.

Data Validation (Optional)

Depending on the configuration and needs, KlearStack may perform data validation to ensure accuracy. 

This can include checks for numerical values, date formats, or other specific criteria.

Output Formats

KlearStack offers the flexibility to output the extracted data in various formats, such as spreadsheets (e.g., Excel), databases, or custom formats, depending on your requirements.

Review and Correction (If Necessary)

Users have the option to review the extracted data and make corrections if the OCR engine encounters any difficulties. This ensures accuracy and reliability.

Automation and Integration 

KlearStack can be integrated into automated workflows.

It can automatically populate databases, accounting software, or other systems with the extracted data.
