Import

Drag in a CSV. We'll do the rest.

Every US bank exports CSVs. Every US bank does it differently. Smart column detection handles the difference, so you don't have to learn each bank's schema before you can track your money.

How it works

Three steps. No spreadsheet wrangling.

  1. 01

    Drop the file

    CSV, XLSX, OFX, or QFX. Drag from your downloads, or paste a path. Parsing happens in your browser — the file doesn't move until you say go.

  2. 02

    Verify the mapping

    Arden guesses every column's role. You can override any of it. Sign-flip toggle has a 2-row live preview so you confirm direction before commit.

  3. 03

    Categorize once

    Tag a few payees. Arden remembers. Every Trader Joe's transaction after that lands in Groceries automatically — no rule-writing.

Under the hood

Three things our pipeline does that matter in the real world.

01

Header detection that survives prefix rows

Some banks (Schwab and TD, looking at you) prefix their CSVs with account-info rows before the real header. Arden scans the first 15 rows to find where the real columns start — no manual cropping required.

02

Sample-value sniffing

Columns literally named "Trans" or "Ref" still get the right role because Arden looks at what the values actually are. Dates parse like dates. Amounts parse like amounts. Tickers match ticker patterns.

03

Sign-flip with a live preview

Some banks export debits as positive numbers. Flip the sign with a single toggle — with a 2-row live preview so you confirm the direction before you commit anything.

File formats

Four formats. One pipeline.

  • CSVEvery US bank exports them. Comma, semicolon, or tab delimiters all work.
  • XLSXExcel exports straight from your bank's web portal. First sheet is used.
  • OFXOpen Financial Exchange — used by Quicken and older bank portals.
  • QFXQuicken's variant of OFX. Same parser, pre-mapped for Quicken's schema.

Indicator-mode CSVs (Dr/Cr columns, used by Navy Federal and some credit unions) are detected automatically — no toggle required.

Coming soon

Plaid too, if you want it.

Auto-refreshing bank and brokerage connections are on the way. Plaid production approval takes a few weeks and we'd rather do it right than ship a broken link flow. When it lands, it'll be an option on the same account — never a requirement, never a gate.

Until then: every feature in Arden works with manually imported data. Nothing is gated behind Plaid.
