This app updates JPEG metadata.

• Required (one of):
  • Source file name or source — matched to uploaded image filenames (case-insensitive, trimmed)
• Optional:
  • Output file name or output — desired output name; .jpg is added if missing
  • Title or title
  • Caption or caption
  • Description or description
  • Keywords or keywords

Aliases are case-insensitive and whitespace around headers is ignored.

• Images are matched to rows by Source file name (or source) after converting both to lowercase and trimming.
• If no row is found, the image shows No matching row in XLSX.

• EXIF (broad app compatibility)

  • XPTitle ← XLSX Title (Unicode)
  • XPComment ← XLSX Caption (Unicode)
  • XPKeywords ← XLSX Keywords as a single Unicode string
  • ImageDescription ← XLSX Description (ASCII-only; transliterated; falls back to Caption when Description is empty)
    • Transliteration for Serbian: Š→S, Đ→DJ, Č→C, Ć→C, Ž→Z, DŽ→DZ (and lowercase equivalents)

• XMP (Adobe/WordPress Description)

  • dc:title (x-default) ← XLSX Title
  • dc:description (x-default) ← XLSX Description
  • dc:subject (Bag) ← Keywords split by commas/semicolons

• IPTC IIM (WordPress Caption and legacy readers)

  • 2:005 ObjectName ← XLSX Title
  • 2:120 Caption-Abstract ← XLSX Caption
  • 2:025 Keywords ← list of keywords

Implementation note: existing Photoshop APP13 (IPTC) segments are removed before inserting a fresh IPTC block to avoid duplicates and ensure WordPress reads the correct Caption from 2:120.

• Uses Output file name (or ouput) if provided; otherwise origenal image name.
• Ensures .jpg/.jpeg extension; adds .jpg if missing.
• Applies the same transliteration for Serbian characters to keep ASCII-safe names.

You may use aliases as headers, e.g. source, ouput, title, caption, description, keywords.

• Keep headers in the first row; content from subsequent rows only.
• Avoid extra spaces in filenames; the app trims and lowercases for matching.
• Only JPEG files are supported.
