Understanding TRNS and SPL Entries in IIF Files

IIF files commonly use transaction structures such as TRNS, SPL, and ENDTRNS records. These entries help QuickBooks organize financial data into balanced accounting transactions.

TRNS Records

TRNS lines represent the main transaction details including:

Date
Account
Transaction amount

SPL Records

SPL lines represent the balancing side of the transaction. These are often linked to bank accounts, expense categories, or income accounts.

ENDTRNS Records

ENDTRNS marks the end of a transaction block inside the IIF structure.

This converter automatically generates these records for every CSV transaction row, helping users create properly structured QuickBooks import files quickly and accurately.
