A few useful answers.
The details that matter before you use BAI2 Viewer.
Which BAI2 records are read?
This version reads complete 01, 02, 03, 16, transaction-text 88, 49, 98 and 99 records. Other continuation placements and bank-specific extensions fail closed.
How are unknown transaction codes handled?
Raw three-digit codes remain visible. Credit and debit are classified only for standard 100–399 and 400–699 ranges; other monetary codes remain unclassified.
Which currencies are supported?
The tested decimal scales are USD, CAD, EUR and GBP with two places, plus JPY with zero. Other currencies are rejected rather than guessed.
Are control totals verified?
No. The parser displays supported records but does not certify account, group or file control totals, or reconcile balances.
How are continuation lines handled?
A type 88 line after a supported type 16 transaction extends its description. Other continuation forms are rejected in this version.
What does CSV contain?
CSV has one row per monetary transaction. Type 890 non-monetary detail is omitted with an explicit warning; Excel also has an account statement sheet.
Do reports leave the browser?
No. Parsing and exports are local. Account numbers, references, filenames and report content are excluded from analytics.
