About Replace Values
Replace Values searches for an exact value across the whole JSON dataset and replaces it with another — e.g. changing all "Y" to "Yes" or "0" to blank.
It is useful for normalizing codes, fixing misspelled values, or swapping placeholders. The replacement applies to all fields in all rows.
Enter the value to find and its replacement in "More settings". Processed in the browser.
