Ledger to Beancount converter

No. The conversion runs entirely in your browser using JavaScript on this page — your journal is never sent to beancount.io or anyone else, and nothing is stored. You can confirm it by disconnecting from the internet and converting anyway: it still works.

Three things bite in practice. Account names: Ledger allows spaces and lowercase, Beancount requires one of five roots followed by capitalized, space-free segments — so 'expenses:home:rent' becomes 'Expenses:Home:Rent'. Amounts: Beancount always writes the number first and the commodity after, so '$84.23' becomes '84.23 USD'. And accounts must be opened before use in Beancount, which Ledger never required. This tool handles all three and tells you every account it renamed.

Virtual postings — the ones in parentheses or brackets — have no Beancount equivalent, because Beancount requires every transaction to balance. Automated transactions ('=') and periodic transactions ('~') likewise have no direct equivalent. Included files must be inlined first, since the converter only sees what you paste. Each of these is commented out in the output and listed with its line number, so nothing disappears silently.

Run bean-check against the output — 'uvx --from beancount bean-check main.bean' works without installing anything permanently. It will catch unbalanced transactions, unopened accounts and syntax problems. Then compare a balance report against the same report from Ledger: if the totals agree, the conversion carried your history across intact.
