Rollback safety

I kept losing time hunting for invoices, so I automated the naming convention. The script parses vendor names, dates, and sequence numbers, then renames files consistently.

A simple HTML interface helps less technical teammates preview changes before committing them.

Challenge

Finance files arrived with inconsistent naming, making reconciliation painful.

Approach

Built a deterministic parser with preview mode so every file follows the same pattern before being renamed.

Outcome

Reduced monthly reconciliation time and slashed the number of misfiled invoices in shared drives.

Highlights
  • Pattern-aware parser covering multiple date formats
  • Preview mode prevents accidental renames
  • Runs locally with zero external dependencies
