Hey Product Hunt — I’m Ezra, the maker of LedgerHarbor.
I built it after seeing how often a simple bank CSV-to-IIF task turns into manual cleanup: different column names, signed amounts vs. separate debit/credit columns, extra balance rows, and uncertainty before importing.
LedgerHarbor lets you upload a CSV, map the fields, review the output, and export an IIF file locally in your browser. Your source file stays on your device while you work.
A couple honest notes:
It’s designed for reviewing and exporting structured transaction CSV data—not every bank export or accounting import is guaranteed to behave the same.
Please review the export and keep a backup before importing it into accounting software.
Standard is a one-time $19.99 purchase, not a subscription.
I’d really value feedback from anyone who handles bookkeeping imports or has dealt with CSV-to-IIF workflows. What part of this process gives you the most trouble?

honestly this looks really useful, the local processing part is a huge plus for privacy. one thing though, would be great if you could save mapping presets for different bank formats so you don't have to set up the columns every single time you import. would save a lot of clicks for anyone dealing with multiple accounts.

@bidavkubra60771 Quick correction from me: LedgerHarbor Plus already includes saved mapping and account profiles for repeat formats. I should have mentioned that in my first reply. I’m going to make that more obvious in the product flow, because it should absolutely save time for people working with multiple accounts or recurring bank exports.

Finally a CSV to IIF tool that actually shows you the mapping before exporting, kind of wish I'd had this last quarter when I was cleaning up a nightmare export. The validation step caught a couple of misaligned columns I would've shipped to QuickBooks otherwise.

@kellyparketl6a Thank you, Kelly, that is exactly the problem I wanted to solve. It is easy to get a CSV export that looks fine at first glance but has a shifted column or balance field hiding in it. I’m really glad the mapping and validation steps were useful. If you run into a particular bank export or edge case that is still frustrating, I’d love to hear about it.
