1. Go to Ordering > Kitchen > Sub-Recipes and click Upload Subrecipes (requires Edit Ingredients).
2. Click Download Template to get a subrecipes.csv file with the columns name, productioncost, costperhour, timetoprepare, baseweight, baseunit.
3. Fill one row per sub-recipe. baseunit must be the numeric ID of the unit; the file is read as comma-separated if the header row contains a comma, otherwise as semicolon-separated.
4. Drag the file onto Upload Subrecipes or browse, then click Import Subrecipes.

Sprwt creates each row as a sub-recipe with manual cost and manual macros (no ingredients attached) and reports "Imported success X lines and Y lines with errors!". Rows whose column count does not match the header are counted as errors.
