Bank Statement PDF to QFX — For Quicken
Quicken's Web Connect format. It is OFX with one addition, and that addition is what decides whether the file loads: without an INTU.BID in the sign-on block Quicken refuses the import and blames the file as a whole rather than the missing tag.
Carries the INTU.BID tag Quicken requires — without it Quicken rejects the file.
The tag Quicken insists on
INTU.BID is present. Files that omit it produce "not a valid Web Connect file", which tells you nothing about what was actually wrong.
No duplicate transactions on re-import
Stable, unique identifiers mean importing the same statement twice does not double your register.
Balances carried across
The closing balance the bank printed goes into the ledger balance, so Quicken agrees with your statement on day one.
