What if the import goes wrong?

It tells you first. Your file is read in your own browser and checked before a single byte is uploaded, and then a practice run resolves every row against your real data and reports what would happen without saving anything. You only press the real button once you have seen the numbers.

Can I bring it in twice?

Yes. Records are matched on their natural key (SKU for products, email for customers, order number for orders) so running the same file again updates rather than duplicates. Fix something in the spreadsheet and re-drop it.

For most businesses there is nothing to do. It is a file and a button. If your data is genuinely awkward, email migrate@sparx.works and we will do the move with you.

← Every platform we move you from

Publishing is solved. The business around it is not.

Posts and pages with their tags intact, and your members list: from the JSON backup and the members export.

This is a Ghost posts, pages and tags export

We can tell from the columns and the file name.

Posts, pages and tags

128 of 129 ready

128 posts, pages and tags ready: 1 row will be skipped.

Must fix

Row 84: this record has no name.

Nothing has been saved yet.

You write. Then everything else needs a different tool.

1

Selling anything means leaving

A book, a workshop, a print, a consulting hour. Ghost is not a shop and does not pretend to be, so anything you sell lives somewhere else with its own customer list.

2

Your members and your customers are different people to the software

The person on the paid tier and the person who bought the book are two records, and nothing tells you they are one human being.

3

The site is the publication and nothing more

No landing pages worth the name, no CRM, no way to run the part of the business that is not writing.

What comes across

Everything in this list is something an importer we maintain actually reads out of your Ghost export. It is generated from that importer, so it cannot promise you something we do not do.

Keep the writing. Add the rest of what you do.

sparx publishes as well as Ghost does and then keeps going: the shop, the customers, the email and the site are the same system. The subscriber who buys the book is one record, because there is only one place records live.

What that changes

Tags survive. Most CMS migrations flatten taxonomy, and you find out later.
Members become customers who can also buy things.
Selling a course, a print or an hour is a switch, not a second platform.

What does not come across

Every migration leaves something behind. Here is ours, so it is not a surprise halfway through.

Stripe subscription state stays with Stripe; paid members come across as members, and billing is re-connected here.
Ghost themes do not transfer.
Newsletters already sent stay in Ghost.

Before you start

Still curious? Read the platform docs, browse the API spec, or book a 20-min architecture call. We don't do high-pressure demos.

No. Everything happens on a copy. You export a file, and your Ghost account carries on exactly as it is. Plenty of people run both for a few weeks before switching their domain over.

Bring it over

Export the file Ghost already makes for you, drop it in, and look at what would happen before anything is saved. Two files, under half an hour.
