よくある質問と回答
技術解説Can I use CONVERT across different worksheets in Excel?↓
Yes. You can reference cells located on other sheets by including the sheet name followed by an exclamation mark, for example: =CONVERT(Sheet2!A2:A10). If the sheet name contains spaces, enclose it in single quotes: ='Q1 Report'!A2:A10.
What is the most common reason for errors in CONVERT?↓
Attempting to convert across different measurement dimensions (e.g. length to weight) returns #N/A.
Does CONVERT work identically in Google Sheets?↓
Yes, CONVERT is supported in both Microsoft Excel and Google Sheets with standard evaluation behavior.
