How do I combine two columns in Excel without formulas?

Open your file or paste rows into SheetCombine, click Combine Columns in the toolbar, pick your columns and delimiter, and click Combine Now. Your merged column appears immediately with no formulas needed.

What spreadsheet and data formats does SheetCombine support?

SheetCombine imports and exports XLSX, ODS, CSV, TSV, Markdown tables (.md), JSON, JSONL, SQL INSERT scripts, HTML tables, YAML, XML, semicolon CSV, and pipe-delimited text.

Does SheetCombine upload my spreadsheet data to a server?

No. SheetCombine runs entirely inside local browser memory using client-side JavaScript. Your rows, client records, and files never leave your device.

100% Client-Side:XLSX, CSV, TSV, Markdown & JSON parsing runs locally in browser memory with zero server uploads.
