About Batch Encode
Batch Encode processes a list of lines at once: each line is encoded or decoded (Base64) separately, then the results are shown line by line in the same order.
It is useful for preparing many values at once — e.g. encoding a list of test credentials or tokens, or copying results into a spreadsheet — without repeating one at a time.
