[英]Throwing custom exceptions and error messages in Google Sheets custom function?
[英]Google sheets custom function error “Result was not a number”
我有一个产生错误的 Google Sheets Apps Script 自定义函数: "Result was not a number" 。 尽管无论应用于单元格的“格式”如何,都不会将数字视为数字,但从自定义函数返回的值。 计算出的值然后不能用于其他内置函数,例如 SUM()。
已经问过类似的问题,请参阅此处、 此处和此处(可能还有其他人...),但不解释如何更改返回类型。
DataTypes 的 google apps-script 文档不清楚如何将您的自定义函数“强制”为特定的返回类型。
链接到带有脚本的示例表。
这是我遇到问题的函数(注意下面不包括 getCell()):
/**
Sum all transactions across sheets that match category and date range.
@param category_name The category to filter on
@param date_min Minimum date in range to filter
@param date_max Maximum Date in range to filter
@param [time] Optional update time/date
@return The sum of transactions that match input criteria
@customfunction

var date_min = new Date(date_min);
var date_max = new Date(date_max);
var date_month = date_min.getMonth();
var date_year = date_min.getYear();
