Frequently asked questions
Is the merge tool really free?
Yes. It needs no account and gives you a number of free merges every day. If you need more, or want a HIPAA-compliant end-to-end solution, contact Tenasol.
Are my files stored?
No. Your files go straight from your browser to storage and are deleted the moment they're merged. The result is held only until you download it and is deleted the moment you do. If you never download it, it's deleted automatically after a short time.
What gets deduplicated?
It depends on the kind of file. For PDFs and images, repeated runs of five or more identical pages are removed, so a long document included twice appears once, and images are turned the way their own orientation information says. For C-CDA documents and FHIR bundles, an entry is removed when it's identical to another, including everything linked to it; free text is removed only when it's 100% identical to other free text. HL7 v2 messages aren't deduplicated: they're combined into one batch exactly as they are.
Can I deduplicate a single file?
Yes, for C-CDA documents, FHIR bundles and PDFs or images: add just one file, and it comes back with its repeated entries merged, or, for a PDF, with repeated runs of pages removed. HL7 v2 needs at least two files, because HL7 v2 messages are combined into one batch rather than deduplicated.
Can I combine different formats together, like a C-CDA document and a FHIR bundle?
Not with this free tool -- it merges several files of the same format into one, not different formats into one. Bring them to a common format first with the free Tenasol Converter, or contact Tenasol about a custom pipeline.
Does the order I add files in matter?
Yes. Files are merged in the order shown in the list, so reorder them with the up and down arrows before merging if it matters for your documents.
Can I look at the merged FHIR bundle before downloading it?
Yes. A merged FHIR bundle is shown as a tree right on the page, and can be opened in the free Tenasol FHIR Viewer, which also shows it as tables, a relationship graph or a readable clinical summary, and can validate it.
