About BMO Statements
Bank of Montreal (BMO) is Canada's fourth-largest bank and the oldest bank in Canada, founded in 1817. Their statements combine traditional banking format with modern features like detailed transaction categorization. BMO's significant US presence means their systems handle cross-border transactions effectively.
Statement Conversion Notes
BMO statements include BMO Rewards information for eligible accounts. The Harris Bank US subsidiary uses similar formatting conventions.
BMO Statement Format Details
Understanding the specific layout and structure of BMO PDF statements helps ensure accurate conversion to JSON. Here is what our parser handles for this bank:
1
BMO Canadian statements are fully bilingual (English/French) with column headers appearing in both languages side-by-side (e.g., "Date / Date", "Description / Description") — the dual-language headers require the parser to recognize either language variant
2
Business statements include an "Exchange Rate" column for multi-currency transactions — the rate shown is the BMO posting rate on the transaction date, displayed as a 6-decimal-place factor (e.g., "0.731450")
3
"Bill Payment" transactions are grouped in a separate sub-section labeled "Bill Payments" (or "Paiements de factures" in French) that appears below the main transaction list — these must be included in the export as regular debit transactions
4
BMO Bank of Montreal (Canada) statements have a different column layout than BMO Harris Bank (US) statements — Canadian statements use DD/MM/YYYY dates while US statements use MM/DD/YYYY; verify the account country before converting
5
Account statements include a "Transaction Sequence Number" (TSN) in the leftmost column — this 10-digit TSN is BMO-internal and is used for tracing disputes but should be excluded from the payee or description fields in the exported data
6
Interac e-Transfer transactions show both the sender/recipient email alias and the message sent with the transfer in the description field — the message text is appended after a dash separator (e.g., "Interac e-Transfer from Jane Doe - Rent April")
Supported Statement Versions
- 2019-2024 personal and business statements from Canada and US (BMO Harris) supported
- Bilingual English/French Canadian statements and English-only US statements both handled
- BMO Investorline combined account statements require splitting before conversion
Known Issues We Handle
- Multi-currency accounts (CAD + USD) may have two separate transaction sections within the same statement document — each currency section must be parsed independently and tagged with the correct currency code
- BMO Harris (US) statements acquired post-Bank of the West merger (2023) may include legacy "Bank of the West" account references in the header during the transition period

2
JSON output provides BMO transactions in a structured, machine-readable format ideal for custom integrations, APIs, or data pipelines. Each transaction includes all available metadata as nested JSON objects.
Converting BMO Statements to JSON (JavaScript Object Notation)
BMO bank statements business statements include an "exchange rate" column for multi-currency transactions — the rate shown is the bmo posting rate on the transaction date, displayed as a 6-decimal-place factor (e.g., "0.731450"). This distinctive format requires specialized parsing to ensure accurate extraction of transaction data for JSON export. When converting BMO statements to JSON, our system recognizes these layout patterns and maps them correctly to preserve data integrity and readability in the output file, maintaining the original structure's accuracy while adapting to JSON's requirements.
JSON exports preserve all critical transaction details from your BMO statements while formatting them for optimal compatibility with your target software. The conversion process maintains data integrity across BMO's date fields, transaction descriptions, debit/credit amounts, and running balances, ensuring nothing is lost or corrupted during the format transformation. This makes JSON a reliable choice for BMO customers needing flexible data export options.
Important note for BMO conversions: BMO statements include BMO Rewards information for eligible accounts. The Harris Bank US subsidiary uses similar formatting conventions.. Our JSON export accounts for these statement-specific details, ensuring the converted data matches your original PDF exactly. This attention to bank-specific formatting nuances is what differentiates our converter from generic OCR tools that may miss critical transaction details.
JSON is a lightweight, machine-readable structured data format that has become the standard for web APIs and modern data interchange. When you export bank statements to JSON, each transaction becomes a structured object with typed fields - dates, amounts, descriptions, and balances are all properly formatted and labeled. This format is ideal for developers building automated financial workflows, integrating bank data into custom applications, or processing transactions programmatically.
When to Choose JSON for BMO
Choose JSON when building automated workflows, integrating with APIs, or processing data programmatically. JSON is the standard for modern web applications and data pipelines. This format is perfect for developers who need to parse transaction data with code, or for businesses using automation tools like Zapier or Power Automate.
Importing BMO Data
JSON files can be parsed directly by any programming language. In Python use `json.load()`, in JavaScript use `JSON.parse()`. For no-code tools like Power Automate or Zapier, use the built-in JSON parser action. The structured format means no column mapping is required - each field is already named and typed.

Frequently Asked Questions
How accurate is BMO statement conversion to JSON?
BMO statements often include foreign currency transactions with exchange rate information. Our converter accurately captures both the original currency amount and the converted value, preserving this critical data in your JSON export with high accuracy even with complex, multi-column statement layouts. Additionally, we handle "bill payment" transactions are grouped in a separate sub-section labeled "bill payments" (or "paiements de factures" in french) that appears below the main transaction list — these must be included in the export as regular debit transactions to ensure comprehensive statement processing.
How long does it take to convert BMO statements to JSON?
BMO statements — including 2019-2024 personal and business statements from Canada and US (BMO Harris) — are fully supported. Processing typically takes 25-50 seconds depending on statement length and transaction count. Our system automatically handles business statements include an "exchange rate" column for multi-currency transactions — the rate shown is the bmo posting rate on the transaction date, displayed as a 6-decimal-place factor (e.g., "0.731450") and applies the appropriate parsing rules for optimal JSON conversion.
Is my BMO statement data secure during JSON conversion?
BMO statements may contain special characters or multi-language text, which we process securely using UTF-8 encoding. All data is encrypted with 256-bit SSL during upload and processing, stored in SOC 2 compliant data centers, and automatically purged within 24 hours. Character encoding preserves data integrity while ensuring your financial information is never shared, sold, or retained beyond the processing window.
How do I parse the JSON file programmatically?
The BMO statement exported to JSON uses a standard structure with typed fields for dates, amounts, and descriptions. In Python, use `json.load(file)` to read the file and access transactions as a list of dictionaries. In JavaScript/Node.js, use `JSON.parse(fileContent)` to convert the JSON string to an object. Each transaction is already structured with named fields, eliminating the need for column parsing or delimiter handling.
Can I use JSON format with automation tools like Zapier or Power Automate?
Absolutely. JSON from BMO statements is ideal for automation workflows. In Zapier, use the "Webhooks" or "Code by Zapier" actions to parse the JSON data. In Microsoft Power Automate, use the "Parse JSON" action with the schema provided in the file. The structured format makes it easy to extract specific fields, filter transactions, and trigger automated actions based on transaction amounts or descriptions.
Can I convert multiple BMO statements at once to JSON?
Yes, you can batch convert multiple BMO statements by uploading them sequentially. Each statement will be processed into its own JSON file with the original statement period clearly labeled. This is particularly useful for catching up on historical data entry or reconciling multiple months of transactions. The converted files can then be imported into your accounting software in chronological order.
