About Excel Magic & our editorial policy

Excel Magic is an independent learning site for everyday spreadsheet problems. Japanese guides live at the root, with English counterparts under /en/.

Legacy URLs, newly written guides

This is a newly built site. It does not imply continuity or affiliation with the former operator. Where external references identify a useful topic, we publish a new guide at the same legacy URL. We do not reproduce the former articles or images.

Editorial policy

1. Show formulas, arguments, and ranges clearly. Explain important limits and update behavior.
2. Consult official Microsoft references and link to relevant documentation.
3. AI assists with drafting articles and code. Publication does not imply execution in every Excel version or review by a native Japanese editor.
4. Inspect code and try it on a copy before using it with important workbooks.

Downloads

CSV samples and VBA source modules are learning materials. They do not contain personal information or recovered business data from the former website.
