QR code batch

Whichever one you name in column, either by its header text or by a 1-based number; leaving it blank encodes the first column. Empty values in the chosen column are skipped before encoding starts.

zip-png and zip-svg package one image file per row; pdf lays the codes out on printable A4 pages instead, perPage codes to a page with a caption under each one, arranged in a near-square grid.

The QR error correction level, one of L, M, Q or H, M by default. A higher level makes the code more tolerant of damage or a logo overlay at the cost of a denser pattern for the same data.

That row is skipped and named in a note after the result, quoting the value that failed and the reason; the batch only stops entirely if every single row fails to encode.

Turn hasHeader off and every row, including the first, is treated as data; the column you name then has to match either that headerless data or a 1-based column number.

ZIP formats name each image after the value it encodes, cleaned to safe filename characters, falling back to qr-1, qr-2 and so on when a value produces an empty name; the PDF output is always called qr-batch.pdf.
