Output Setup

What the formatter does.

The source values stay as text so IDs, ZIP codes and leading zeros are not silently changed by the converter.

Clean Header

Bold dark header row, frozen in place with Excel filters enabled.

Readable Columns

Left-aligned data, sensible automatic widths and alternating row shading.

Smart Links

URL fields become short blue Excel links such as “Download File” and “View Order.”

Batch Workbook

Each selected CSV becomes its own safely named worksheet in one .xlsx file.

What’s New in v1.3

Restored interactive formatting controls: header-color picker, checkbox options, live five-row preview, configurable filters/freeze/banding/alignment/column widths, and the familiar short blue-link option. Multi-file and local-processing behavior remain intact.

Privacy

Your CSV stays on your device.

The selected CSV files are read by your browser to create the Excel workbook. This tool does not upload those files to DesignAlot.
