ohada-financial-extractor 0.1.0

Extract and normalize financial data from OHADA-compliant Excel financial statements (DSF)

OHADA Financial Extractor

Extract and normalize financial data from OHADA-compliant Excel financial statements.

Overview

This library automates financial data extraction from Excel files following OHADA (Organization for the Harmonization of African Business Law) accounting standards, used by 18 African countries.

What It Does

• Extracts Balance Sheets (Bilan Paysage), Income Statements (Compte de Résultat), and Cash Flow Statements (Tableau des Flux de Trésorerie)

• Normalizes data with Gross/Amortization/Net decomposition for fixed assets

• Consolidates multi-year financial data

• Exports to JSON for downstream analysis

Why It Matters

Financial institutions across OHADA zone countries spend significant time:

• ✗ Manually retyping financial statement data

• ✗ Restructuring Excel files line-by-line

• ✗ Validating data integrity across years

This library eliminates those bottlenecks:

• ✓ Automated extraction from standard Excel formats

• ✓ Structured JSON output

• ✓ Multi-year period aggregation

• ✓ Data validation checks

Quick Start

Installation

pip install ohada-financial-extractor

Basic Usage

from ohada_extractor import FinancialExtractor
from ohada_extractor.formatters import OHADAJSONFormatter
import json

# Extract from Excel
extractor = FinancialExtractor()
statement = extractor.extract_from_excel('financial_statement.xlsx')

# Convert to JSON
json_output = OHADAJSONFormatter.to_json(
    statement=statement,
    indent=2
)

# Use or save
data = json.loads(json_output)
print(f"Total Assets: {data['balance_sheet']['assets'][-1]}")

Supported Statements

Balance Sheet Asset (Bilan Paysage)

• 29 accounts (AD-BZ)
• Tracks: Gross, Amortization, Net values
• Assets split: Fixed assets, Current assets, Cash

Balance Sheet Liability (Bilan Paysage)

• 28 accounts (CA-DZ)
• Tracks: Net values
• Liabilities split: Equity, Long-Term Debt, Current Liabilities, Short Term Debt

Income Statement (Compte de Résultat)

Cash Flow Statement (Tableau des Flux de Trésorerie)

• 25 accounts (ZA-ZH)

Metadata Extraction (NEW)

The extractor now automatically parses company metadata from DSF notes and headers, including:

• Legal form
• Fiscal regime
• Country (headquater)
• Year of creation
• Currency
• etc.

Metadata is available immediately after extraction:

from ohada_extractor.core.extractor import FinancialExtractor
from ohada_extractor.core.metadata_extractor import CompanyMetadataExtractor

# Initialize extractor
extractor = FinancialExtractor()
    
# Extract data
statement = extractor.extract_from_excel("financial_statement.xlsx")

print("\n--- Building company metadata from statement ---")
statement.metadata = CompanyMetadataExtractor.extract_from_statement(statement)

metadata = statement.metadata

print(metadata.currency)
print(metadata.legal_form)
print(metadata.regime_fiscal)

Metadata is fully JSON‑serializable and can be exported:

metadata_dict = metadata.to_dict()

This enables automated KYC, and regulatory reporting workflow.

Notes Extraction (NEW)

The extractor now includes 23 OHADA Notes (Annexes) engine, parsing structured and unstructured notes such as:

• Fiche R2 — Company identity
• Note 31 — Repartition du résultat et autres elements sur les dernières années
• Accounting policies
• Commitments & guarantees
• Tax regime
• Share capital information
• Workforce details

Notes are extracted automatically:

statement = extractor.extract_from_excel("financial_statement.xlsx")

# Retrieve by key
note = statement.get_note("note3a")

# Retrieve by human-readable name
note = statement.get_note_by_name("IMMOBILISATION BRUTE")

Each note includes:

• name
• raw_value
• preprocess_value

Notes can be exported to JSON for auditing or BI tools.

Features

• ✅ Multi-file period aggregation (2-5 years)
• ✅ Automatic data validation
• ✅ JSON-serializable output
• ✅ Account code standardization (OHADA)
• ✅ Gross/Amort/Net decomposition for assets
• ✅ Support for 18 OHADA zone countries

📊 Visualization Layer (NEW)

The library now includes a visualization module for OHADA financial statements.

Static 4×2 Overview Dashboard

Grouped, stacked, waterfall, and cashflow charts in a single figure:

from ohada_extractor.visualization import plot_overview_dashboard_clean
plot_overview_dashboard_clean(statement)

Dynamic Tabbed Dashboard

Interactive dashboard with tabs for:

• Assets
• Liabilities
• Income
• Cashflow

from ohada_extractor.visualization import plot_ohada_tabs_dynamic
plot_ohada_tabs_dynamic(statement)

Streamlit Integration

A ready‑to‑use Streamlit app is included:

streamlit run examples/example_visualization_streamlit.py

This enables instant deployment of dashboards for analysts, auditors, and credit officers.
