plsql - Formatting SQL WHERE Conditional Values

I am looking to see if there is a way to format conditional values in batch instead of manually typing. For example, I am filtering on 5 digit codes in SQL, my source of the codes is in Excel in list form. There can be hundreds of codes to add to a SQL WHERE statement to filter on, is there tool or formatting methods the will take a list of values and format with single quotes and comma separation?

From this:

30239
30240
30241
30242

To this:

'30239',
'30240',
'30241',
'30242',
...

Then, these formatted values can be pasted into the WHERE clause instead of manually typing all of this out. Again, this is for hundreds of values...

I used to use BrioQuery that had functionality to import text files to be used in filtering, but my current qry tool, TOAD Data Point does not seem to have this.

Thank you

Look into SQL*Loader. Create s staging table to contain the imported values. Use loader to populate the stage table. Then modify your query to reference the stage table; it becomes something like:

Select ... 
 where target_column_name in (select column_name from stage_table).

The structure "where in ( select)" may not be the best for performance, but once loaded you will have all the facilities SQL offers at your disposal.

It has been a few years since I've used TOAD but as I remember it has an import functionality. There are other tools for loading data into Excel into Oracle. SQL*Loader just happens to be the one Oracle supplies with the RDBMS.
