About this Tool
Use Remove Empty Columns to clean tables that contain unused fields. The tool identifies columns where every data cell is empty, optionally ignore whitespace, and preserve or remove empty headers based on user choice. It is focused on reducing unnecessary columns while keeping non-empty fields safe.

Frequently Asked Questions
What counts as an empty column?
Usually a column is empty when all data cells are blank after optional trimming. Header-only columns are treated according to the selected option.
Can I preview columns before removal?
Yes. The tool should list detected empty columns and let the user confirm before applying changes.
Are partially empty columns removed?
No. Columns with any meaningful data should remain unless the user explicitly selects a stricter rule.
What file sizes are practical in the browser?
Small and medium tables are the best fit. Very large files can use a lot of memory because parsing, previews, and exported results all live inside the browser tab.
