Excel Quick Tools

Clean Excel data and add prefixes or suffixes to columns, all processed locally.

Excel One-Click Processing Assistant is a lightweight tool for quickly processing local Excel and CSV files. The current version supports adding custom prefixes or suffixes to file names and generating new result files without changing the originals. More productivity features are planned for future releases, including batch file renaming, worksheet and column operations, data cleaning and formatting, file merging and splitting, format conversion, duplicate-data handling, template-based processing, and automated task workflows. All processing is designed to be simple, efficient, and privacy-friendly for local files. Local Excel files can be extended directly in the browser for specialized processing, without requiring users to move their data into a separate system.
