Only mapping and export settings are saved. Spreadsheet values are never stored.

Processed locally. CSV rows and generated values stay in this browser.

Map a CSV to scannable output

Use a header row to map the value to encode and optional label, quantity, filename and format columns. The batch preview makes column choices and row errors visible before export.

Drop CSV

Open a comma-, semicolon-, pipe- or tab-delimited file directly in the batch importer.

Paste spreadsheet data

Paste rows copied from a spreadsheet when a separate CSV file is unnecessary.

Keep filenames safe

Use a filename column or template; collisions receive deterministic suffixes.

Specifications

Column mapping

Value is required; label, quantity, filename and format are optional.

Output

SVG or PNG ZIPs, code sheets and CSV reports; mapped values can continue to Labels for PDF or ZPL.

Validation

Row-level format checks run before export; decode verification scope is recorded in the report.
