If I use e.target.value.toUpperCase() than I get key in object also uppercase. I would like to keep default structure but values transform to uppercase.
This variant originalInputValueFormat: valuesArr => valuesArr.map(item => item.value).join(',') change structure of array.

Sorry for the stupid question.

I feel this is an XY question.

Why do you want the input values to be uppercase? why is this important to you?

[chefranov]

I send output array to backend after then I filter array on backend with array from Tagify. For me important have values in uppercase because in backend array I have values in uppercase.

I tried like this by it doesn't work for me

   originalInputValueFormat: valuesArr => valuesArr.map(item => {
      const container = {};
      container[item.value] = item.value.toUpperCase();
      return container;
    })

what does it matter if the values are in uppercase or not, it's not important at all. You can change to uppercase while comparing in the backend.

Try this:

originalInputValueFormat: valuesArr => 
  valuesArr.map(item => ({...item, value: item.value.toUpperCase()}))
