How to Extract Data from Contracts Using AI

What Is AI Contract Data Extraction?

AI contract data extraction is the process of identifying and retrieving specific information from contracts using artificial intelligence.

Rather than simply converting a PDF into text, the goal is to organize important information into structured fields that can be reviewed, searched, and reused.

For example, a service agreement might contain:

• Client and supplier names
• Contract reference number
• Effective and expiration dates
• Payment amounts and conditions
• Renewal and termination terms
• Confidentiality clauses
• Contractual obligations

With structured extraction, these details can be represented as separate data fields instead of remaining scattered throughout the document.

This process is part of a broader approach to AI document data extraction, where information from different document formats is organized into usable data.

What Data Can Be Extracted from Contracts?

The information you extract depends on the type of agreement and your business requirements.

Here are some common contract data fields:

Consider a company that manages hundreds of supplier agreements. Its finance team may primarily need payment terms and contract amounts, while its operations team may need effective dates, renewal conditions, and service obligations.

Instead of extracting every sentence, the company can define the information each workflow requires. The key is to extract useful information, not simply more information.

Why Is Manual Contract Data Extraction Difficult?

Manual contract review can work when dealing with a small number of documents. However, extracting information becomes more challenging as the volume and variety of contracts increase.

Contracts Have Different Structures

A payment clause might appear under "Fees" in one agreement and "Commercial Terms" in another. Similarly, an expiration date could appear on the first page, inside a table, or within a paragraph near the end of a document.

A process that relies on fixed positions or identical layouts can therefore struggle with contracts from different sources.

Important Information Is Spread Across Multiple Pages

A single agreement can contain several relevant dates, monetary amounts, and legal conditions. For example, the signature date may differ from the effective date, while the renewal date may depend on a notice period described elsewhere.

Extracting the correct value requires understanding which piece of information corresponds to the requested field.

Scanned Contracts Require Additional Processing

Some contracts are stored as scanned PDFs rather than digitally generated documents. These files may not contain selectable text.

Optical Character Recognition (OCR) is used to recognize the text before the information can be organized into structured fields.

However, recognizing text is not the same as identifying the information a business needs. The difference between OCR and data extraction becomes particularly important when working with scanned agreements containing multiple dates, amounts, and clauses.

Manual Copying Introduces Errors

Entering contract data into spreadsheets or internal systems can result in missing values, incorrect dates, or inconsistent formatting. A structured extraction workflow helps reduce repetitive data entry, although extracted results still need appropriate validation.

How to Extract Data from Contracts Using AI

AI-based extraction follows a relatively straightforward process: upload the contract, identify the required fields, process the document, review the results, and export the information.

Here's how to perform these steps using Heyyel Data Extractor.

Step 1: Upload Your Contract

Start by uploading the contract you want to process. Heyyel Data Extractor supports common document formats, including PDF, JPG, PNG, WebP, and TIFF.

This means you can work with digitally generated PDF contracts as well as scanned agreements stored as images. For better results, use a document with clear text and complete pages.

Step 2: Select the Contract Preset

After uploading the document, select the Contract preset. The preset provides suggested fields for extracting common contract information.

You can adjust these fields to match your requirements rather than relying on a fixed extraction structure.

For agreements with more specialized requirements, custom data extraction lets you define the specific information you want to retrieve.

Step 3: Define the Information You Want to Extract

The next step is to specify the fields you need.

Clear field names help distinguish information that may look similar. For example, using effective_date and signature_date as separate fields is more precise than creating a single field called date.

You can also add extraction hints to provide context. An example hint for effective_date would be:

Extract the date on which the agreement becomes effective, not the date on which it was signed.

For a termination field, you might use:

Extract the clause describing the conditions and notice period required to terminate the agreement.

These instructions help define the intended output, particularly when documents contain multiple related values.

Step 4: Run the AI Extraction

Once the required fields are configured, run the extraction. The system processes the document and organizes the identified information according to the selected structure.

Instead of returning the entire contract as unstructured text, the resulting dataset focuses on the fields you specified.

Review the extracted values against the original document, especially for dates, payment obligations, and important contractual conditions.

Step 5: Export the Results as JSON or CSV

Once the results have been reviewed, the extracted data can be exported in JSON or CSV format.

JSON is useful for structured data processing and software workflows, while CSV is convenient for spreadsheets and tabular reporting. The appropriate format depends on how your team plans to use the extracted information.

Example: Extracting Contract Data into JSON

Consider a fictional service agreement between two companies. The contract contains the following information:

• Client: Northstar Retail Ltd.
• Supplier: Atlas Digital Services
• Effective date: January 1, 2026
• Expiration date: December 31, 2026
• Contract value: EUR 24,000
• Payment terms: Monthly payments of EUR 2,000
• Renewal: Automatically renews for 12 months unless either party provides 30 days' notice.

Instead of manually transferring these details into a spreadsheet, the information can be organized into structured fields.

An illustrative JSON output would look like this:

{
  "contract_title": "Service Agreement",
  "client_name": "Northstar Retail Ltd.",
  "supplier_name": "Atlas Digital Services",
  "effective_date": "2026-01-01",
  "expiration_date": "2026-12-31",
  "contract_value": 24000,
  "currency": "EUR",
  "payment_terms": "Monthly payments of EUR 2,000",
  "auto_renewal": true,
  "renewal_period": "12 months",
  "termination_notice": "30 days"
}

This fictional example illustrates the intended data structure, not an actual extraction result or accuracy benchmark.

Each field now has a clear name and a corresponding value. The data can be reviewed, compared with other agreements, or used in an internal reporting workflow without repeatedly reading the entire PDF.

Contract OCR vs AI Contract Data Extraction

OCR and AI data extraction are related, but they solve different problems.

OCR recognizes text. AI data extraction identifies and structures the information you need.

For example, OCR might recognize this sentence in a scanned contract:

The agreement shall remain effective until December 31, 2026.

Structured extraction can then identify the relevant field:

{
  "expiration_date": "2026-12-31"
}

The distinction becomes particularly important when a contract includes several dates or conditions. OCR makes the text accessible, while structured extraction maps information to predefined fields.

Common Use Cases for Automated Contract Data Extraction

Structured contract data can support several business processes.

Contract Administration

Administrative teams can extract contract references, parties, dates, and other identifying information to maintain organized contract records.

Finance and Accounting

Finance teams can retrieve contract values, currencies, payment schedules, and billing conditions for reconciliation and reporting.

Procurement and Supplier Management

Procurement departments can extract supplier details, service periods, renewal dates, and termination conditions from vendor agreements.

Legal Operations

Legal teams can use extracted clauses and metadata to locate relevant provisions and prepare contracts for further review. AI extraction supports information retrieval, but it does not replace legal interpretation or professional judgment.

Reporting and Document Management

Organizations can collect consistent fields from different contract documents and export them into structured datasets for further analysis.

Best Practices for Accurate Contract Data Extraction

AI-based extraction can reduce repetitive work, but a reliable process still depends on how the fields are defined and validated.

Use Precise Field Names

Avoid vague names such as date, amount, or company. Prefer contract_effective_date, annual_contract_value, or supplier_legal_name.

Separate Different Contractual Dates

Signature dates, effective dates, renewal dates, and expiration dates can have different meanings. Treat them as separate fields whenever your workflow requires them.

Add Context for Complex Fields

A field such as termination_clause may require a clear instruction defining which information should be retrieved.

Extraction hints help explain the expected meaning. This is especially useful when you need to extract specific data from PDF documents containing several similar dates, monetary values, or contractual provisions.

Review Critical Information

Validate financial values, deadlines, renewal conditions, and clauses that could affect business decisions. An extracted clause should be checked against its original wording and context before being used for legal or operational decisions.

Handle Missing Information Carefully

Not every contract contains every requested field. Establish how missing information should be represented so that an absent clause or value is not confused with a confirmed negative result.

When Should You Automate Contract Data Extraction?

Automation becomes particularly useful when a business regularly processes contracts containing similar categories of information, even if the documents use different layouts.

For example, a company may receive service agreements from multiple suppliers and need to collect the same fields from each document. Instead of manually reading each agreement and entering its information into a spreadsheet, the company can define a consistent extraction structure and review the resulting records.

Manual extraction may still be appropriate for occasional documents or situations requiring extensive interpretation. The objective is not to eliminate human review, but to reduce repetitive information collection and make relevant data easier to access.
