info What is SkuSync?
SkuSync converts Shopify and SHOPLINE CSV or SHOPLINE 1.0 XLSX product exports into three downloadable formats:
Field types and validation rules for product data. This file is not Schema.org Product markup or a product feed.
A Markdown catalog summary based on the llms.txt proposal. Review the content and links before publishing it.
Product records with one JSON object per line for processing or import into a compatible system.
File conversion happens in your browser. Downloads are local files; SkuSync does not deploy llms.txt or NDJSON to your store or submit a feed to another service.
Frequently Asked Questions
What is llms.txt and how do I use it? expand_more
llms.txt is a proposed Markdown convention for presenting site information to language model tools. Review the generated catalog summary and product links, then deploy it on your website. Downloading it does not publish it or guarantee crawling, AI mentions, or rankings.
How do I convert Shopify or SHOPLINE exports with SkuSync? expand_more
Enter your store URL, upload a Shopify or SHOPLINE product CSV or a SHOPLINE 1.0 XLSX export, review the detected format and data preview, then download JSON Schema, llms.txt, NDJSON, or a ZIP archive. File conversion runs in your browser.
What is the difference between JSON Schema and NDJSON output? expand_more
JSON Schema defines field types and validation rules. It is not Schema.org Product markup or a product feed. NDJSON contains product records with one JSON object per line. Review these records before deploying them or importing them into another system.
Are my product files uploaded to a server? expand_more
SkuSync parses product files and generates downloads locally in your browser without uploading those files to a server. The separate AI Readiness Checker sends the website URL you enter to an external scanning service.
Which export formats does SkuSync support? expand_more
SkuSync supports Shopify product CSV, SHOPLINE 2.0 product CSV, and SHOPLINE 1.0 XLSX exports. It detects the format from the export headers. Preserve the original headers and review the preview before using the output.
Is the NDJSON output guaranteed to meet OpenAI feed requirements? expand_more
No. NDJSON is a serialization format, and generating a file does not establish compliance or acceptance by OpenAI or another service. Review the destination's current requirements, verify product values and required fields, and validate the feed before submission. SkuSync does not submit or deploy it.
Can I upload the JSON Schema to Google Merchant Center? expand_more
The JSON Schema download contains validation rules rather than product records. It is not a Merchant Center product feed or Schema.org Product JSON-LD. Prepare actual product data in a supported destination format and validate it against current requirements. SkuSync does not guarantee Merchant Center compliance or approval.
