It validates the rows, spaces scheduled content on a five-hour cadence, then loops through each row to download its image and upload it to PinFlow. For each valid row, it schedules corresponding Pinterest, Instagram, and Facebook posts before moving to the next row.\n\n### Setup steps\n\n- Configure the form trigger so it accepts the campaign spreadsheet as a binary file upload.\n- Ensure the spreadsheet has the columns expected by the validation code, such as image URL, post text/caption, destination account or board fields, links, and any timing-related fields used by the workflow.\n- Set up PinFlow credentials on all PinFlow nodes and verify the selected Pinterest, Instagram, and Facebook destinations are available.\n- Review the extract-from-file nodes to confirm each file format reads the correct sheet, delimiter, headers, and binary property from the upload.\n- Test with a small campaign file first to confirm images download successfully and posts are scheduled at the intended five-hour interval.\n\n### Customization\n\nAdjust the validation code to change required columns, default values, or the five-hour scheduling interval. The platform scheduling chain can also be modified to add, remove, or reorder social networks."
