Features

• Instant Extraction: Uses the specific GetTransactions API to fetch data 100x faster than scrolling.
• Deep History: Easily download transactions from years ago without waiting for the page to load.
• Customizable Output: Choose exactly which columns you want (Date, Description, Amount, Category, Type, Account, Notes, Labels).
• Modern UI: Beautiful interface with Dark Mode support and Quick Date presets (YTD, Last Year).
• Instant Stop: Cancel huge extractions immediately without losing data—what you've fetched is saved.
• Smart Export: Automatically generates All Data, Income Only, and Expenses Only files.
• One-File BudgetLens Export: The default BudgetLens Bundle combines transactions, both wealth histories, the current five-category breakdown, and available account sources in one versioned JSON file.
• Wealth History: Export the full Net Worth and Investment graph series as separate, date-filtered CSV files.
• Current Net Worth Breakdown: Export current Cash, Investments, Property, Credit cards, and Loans totals to net_worth_breakdown_<date>.csv, plus available cash, investment, and property source balances to wealth_accounts_<date>.csv. These snapshots are not filtered by the selected historical date range.

Quick Start

1. Install the Extension:

   • Clone this repository or download the files.
   • Open Chrome and go to chrome://extensions/.
   • Enable Developer mode (top right toggle).
   • Click Load unpacked and select the extension directory.

2. Export Data:

   • Go to Credit Karma Transactions.
   • Click the extension icon.
   • Select your date range (or click "Last Year").
   • Leave BudgetLens Bundle selected for one JSON file containing transactions and all supported wealth data.
   • Choose the individual CSV exports when you need separate transaction or wealth files. Complete Net Worth creates the total history plus current asset/debt segment totals and the detailed source rows Credit Karma makes available.
   • Choose Current Snapshot Only when you want the current breakdown and account balances without a historical date range.
   • Click Export Selected Data.
   • Watch the progress indicator and wait for your CSV files!

Analyze Your Data

Once you have your CSVs, you can use them with:

1. BudgetLens: Modern web dashboard for visualizing your financial data.
2. TMOAP Budget Tool: Comprehensive spreadsheet for detailed financial analysis.
3. Any spreadsheet software (Excel, Google Sheets, Numbers).

Changelog

Version 2.2 (July 2026)

• Added a one-file, versioned BudgetLens JSON bundle containing transactions and all supported wealth data.
• Added current snapshot exports for Cash, Investments, Property, Credit cards, and Loans totals, plus individual cash, investment, and property sources. Credit Karma's captured responses do not provide per-source history, so these files are intentionally independent of the date-range fields.

Version 2.1 (July 2026)

• Added separate CSV exports for Net Worth and Investment graph values.
• Wealth exports use the complete graph dataset and respect the selected date range.
• Updated transaction exports to preserve user-corrected categories through the paginated transactionsHub API, with safer pagination and a fallback for incomplete responses—thanks to @CarterDunn for the contribution.
• Added automatic content-script reinjection and a raw API JSON debug export for easier troubleshooting.

Version 2.0 (January 2026)

• Major Rewrite: Switched to GraphQL API-based extraction.
• New UI: Complete visual overhaul with Cards, Dark Mode, and compact layout.
• Column Selection: Users can now filter specific columns from the CSV.
• Performance: Extraction is now near-instantaneous.
• Robustness: Better error handling and "Instant Stop" functionality using AbortController.

Version 1.2 (March 2025)

• Added real-time transaction counter.
• Basic "Stop" functionality.
• Adaptive scrolling speeds.
