A CSV and Excel importer with column mapping, validation and background processing. A case study by Viktor Petrenko, Full-Stack Developer (Laravel & Vue).

## Challenge

New customers of Shiftly, a workforce scheduling app, had to send their data to support for manual import. Onboarding took two weeks and imports often failed on bad dates or duplicates.

## Solution

I built a self-serve importer: upload, automatic column mapping, row-level validation with clear error messages, preview, and background processing that handles files with 200,000 rows.
