Barclays SBL Reconciliation — runs in your browser

File 1 = YOURS (I2255 billing)  |  File 2 = THEIRS (counterparty / PHLHK billing). Everything runs on this device — nothing is uploaded to any server.
Both files are parsed locally in your browser. Nothing leaves this device except stock identifiers sent to look up HK codes (only if a code isn't already known).
