Automated API XLS parsing for Dynamics Finance ERP intelligence
Automated API XLS parsing for Dynamics Finance ERP intelligence converts each legacy Excel workbook attached to a record into searchable passages, so the assistant answers from the file rather than from fields someone typed.
How does automated API XLS parsing feed Dynamics Finance ERP intelligence?
Automated API XLS parsing for Dynamics Finance ERP intelligence converts each attached legacy Excel workbook into passages when the file is saved, so the assistant can cite the file instead of guessing from record fields.
Where the legacy Excel workbook sits in Dynamics Finance
Dynamics 365 Finance keeps the file as a document attachment on the vendor, purchase order, or invoice. The typed fields on that record are already searchable. The legacy Excel workbook is not, until automated API XLS parsing copies its words into passages keyed to the same record. ERP intelligence that only reads the fields is intelligence about what a person typed, not about what the file says.
What a legacy XLS actually yields
An .xls file is a BIFF workbook inside an OLE container. The reader walks records: shared strings, labels, numbers, and formula results that arrived as text. The output is one table of those cell values in encounter order. A workbook with no cell text is an error, not a silent empty index. It is not an .xlsx zip and it is not a CSV.
The API call that feeds Dynamics Finance
A Power Automate flow or a Finance integration can POST those bytes when the attachment is saved. The response is JSONL, one passage per line, with the record id in metadata for the retrieval store beside Dynamics Finance. Asking a model to reread the legacy Excel workbook inside chat for every question never builds that index. Automated API XLS parsing runs when the file is saved, once, and later questions retrieve.
What the answer is allowed to cite
After a clean parse, an answer should cite the passage and the legacy Excel workbook it came from. A file that yields no text is a skip, named as a skip, not a blank passage that crowds real hits. The parsers are Remade with Rust crates, and RAG Converter is part of MATA. The longer note on this format is RAG for Excel.
