Budget Bandit gives you five file importers plus live bank linking. Which one you want depends on where your data is coming from and whether you are moving a whole budget or just adding transactions to an account. **Every import creates a brand-new budget or adds to an existing account. An import never overwrites or merges into a budget you already have.** The three full-migration importers (YNAB, Monarch, Actual) each create a separate new budget. CSV and OFX/QFX add transactions into an account you choose, inside the budget you are already in. Either way, your existing budget is left untouched. ## Pick your path Brings accounts, categories, transactions, and your monthly assignments into a new budget. Two CSV files become a new budget with accounts, categories, and transactions. Reads your Actual export and builds a new budget from it. Map columns and add transactions to an account you choose. A structured bank or Quicken file — no column mapping needed. Skip files entirely and let transactions sync on their own. ## Decision guide | You have | Use | What you get | | ------------------------ | ------------------------------------------------ | ----------------------------------------------------------- | | A full YNAB budget | YNAB | New budget: accounts, categories, transactions, assignments | | A Monarch account | Monarch | New budget: accounts, categories, transactions | | An Actual Budget file | Actual | New budget: accounts, categories, transactions, assignments | | A bank CSV download | CSV | Transactions added to one account | | A `.ofx` or `.qfx` file | OFX/QFX | Transactions added to one account | | A bank that Plaid covers | Bank link | Transactions sync automatically | ## How the two kinds differ **Whole-budget migrations (YNAB, Monarch, Actual)** build a complete new budget so you can switch to Budget Bandit without losing structure. Because they always create a new budget, you can run them safely even if you have been experimenting already — nothing you have built is touched. **Transaction imports (CSV, OFX/QFX)** add rows to a single account you pick. They run duplicate detection so re-importing an overlapping file does not double your history. Use these to top up an account that is not on a bank feed. ## After any import Imported transactions arrive in your To Review queue. Confirm and categorize them, and any rules you have set apply automatically to matching rows. ## If rows do not come through See Why rows did not import for skipped dates, bad amounts, and duplicate handling. ## Related Exactly which columns and formats are expected.
