Purpose
What this converter does
Upload the original Spanish Norma 43 modality 1 file. Confirm the true century of YYMMDD dates based on bank records (1800, 1900, 2000 or 2100). The Java backend validates the records, account blocks, balances and complements. The workbook contains Summary, Transactions, Balances, Accounts and SourceRecords; original record 23/24 metadata does not become extra monetary transactions.
Workflow fit
When this route is useful
Examine bank movements, original records, accounts and source-supported balances separately in five worksheets. Account identifiers and high-precision amounts are preserved as text where needed to avoid Excel rounding or lost leading zeroes.
Implementation note
What to expect
No opening/closing balance is fabricated if the source lacks one. Currency and signs follow the bank source; 23/24 complements do not double-charge. Formula-like text is neutralized, and backend warnings indicate precision protections. This workbook is not a certified bank feed or universal re-import format.
