When I export data in Overview, the keyword search values 0-10 are exported as an empty field. This makes it difficult to create keyword analysis. I suggest a compromise and instead of an empty field, export an average of 0-10 for this field, which is a value of 5.

0-10 or 5 means that very few people are searching for the keyword. 0 means no one is looking. And that's a big difference.
