All tools

Pick a tool, upload your file, get your result. Everything runs in your browser.

Merge multiple Excel or CSV files - stack rows on top of each other, or join by a shared key column.

Split one spreadsheet into multiple files - one per unique value in a column.

Find rows that were added, removed, or changed between two spreadsheet versions.

Filter rows by one or more conditions - equals, contains, greater than, and more - then download the results.

Replace all formulas with their computed values across every sheet - like Paste Special → Values for the whole file.

All tools process files locally in your browser. Nothing is uploaded.
