Capabilities
Features built for real Excel work
Custom Delimiter Selection
Pick the exact separator, comma, tab, or semicolon, so any flat-file layout splits into the correct columns with zero parsing errors.
Bulletproof Date Handling
Declare whether source dates are US (MM/DD/YYYY) or local (DD/MM/YYYY) and the smart date engine converts them to true Excel dates, never scrambled or flipped into text.
Safe 1M+ Row Splitting
CSVs that exceed Excel's ~1,000,000-row limit are safely split into numbered workbooks or sheets, so no rows are ever lost.
Smart Header Control
Set the header row number to skip logos, titles, and blank rows, and optionally repeat the header and pre-header context across every split file.
Smart Sub-Folder Mapping
Automatically recreates your source folder hierarchy in the destination, saving each workbook into a matching sub-folder so large jobs stay perfectly organized.
Export-Ready Output
Auto-fit column widths, control whether existing files are overwritten, and optionally open the destination folder when the run finishes.
Clean, Safe Workflow
A zero-clutter interface writes to a separate destination folder, leaving your raw CSVs untouched for a clear audit trail and zero learning curve.

FAQ
Frequently asked questions
What does the Multiple and Large CSVs to Multi-Workbook Generator do?
It converts entire folders of CSV files, including deeply nested subfolders, into clean, native Excel (.xlsx) workbooks in seconds.
Will it scramble my dates?
No. You declare whether source dates are US (MM/DD/YYYY) or local (DD/MM/YYYY) and the smart date engine converts them to true Excel dates without flipping them or turning them into text.
What happens with CSVs larger than Excel's row limit?
Files over Excel's ~1,000,000-row limit are safely split into numbered workbooks or sheets, with headers repeated on each part, so no rows are lost.
Are my original CSV files modified?
No, your source CSVs are never touched; the workbooks are written to a separate destination folder.
