Excel Batch Cell Editor is a Chrome add-on tool developed by 森と川. It serves the purpose of making bulk modifications to specific cells within multiple Excel files. The tool offers a user-friendly interface with clear steps for efficient editing.

Upon clicking the "File Selection" button, users can upload multiple Excel files simultaneously. They can then specify the target sheet for modifications, using a flexible fuzzy search setting. Defining the search criteria involves selecting rows or columns along with the search value.

Users can also indicate the replacement value and its position in rows or columns for the desired modifications. By clicking "Add Modification," users can repeat steps 2 to 5 for multiple edit locations. Finally, with a click on "Download All Modified Files," users can conveniently download all files with the applied changes.
