QIF converter

The QIF converter ingests a QIF file or pasted data and converts it into OFX, QFX, or CSV formats for use in modern financial software. It preserves core transaction details such as date, amount, payee, memo, category, and check or reference numbers, and can retain or re-map accounts during the export. The tool is aimed at personal finance users migrating from legacy exports, bookkeepers reconciling client data, and small businesses consolidating records across multiple accounts. It supports common QIF variants and is designed for reliable data migration rather than in-tool editing.

Under the hood, the tool parses QIF with a robust, stateful parser that recognizes sections and transaction lines, builds an internal, canonical transaction model, validates date and amount formats, and then serializes to the selected target format. It supports single-file or batched processing, preserves transaction order, and offers optional mappings for accounts and categories. Currency codes present in the source are preserved; currency conversion is not performed unless explicitly requested. The approach prioritizes data integrity and auditable results.

Key differentiators include multi-format output from a single input, optional account and category mapping, per-transaction validation, and concise error summaries for problematic records. This enables reliable data migration, faster onboarding of new finance software, and auditable historical records for advisors. Typical use cases include migrating a year of transactions, preparing data for tax software, or sharing archival records with clients without manual re-entry. The tool is designed to be deterministic, predictable, and suitable for both individuals and small teams.
