Generate Based on Spec

Upload your spec file — supports one tab per domain or all domains in a single Variables tab

How it works — two accepted spec layouts:

One tab per domain

Tabs named as 2-letter SDTM codes (e.g. DM, AE, VS) or SUPP* become datasets. Other tabs (e.g. Codelists) are ignored.
Each tab's Variable Name column lists the variables for that domain.

All domains in one tab

In both cases every dataset shares the same subject IDs so you can join by USUBJID.

Excel (.xlsx, .xls) CSV (.csv)

Files are processed server-side only and not stored.

Expected Excel structure:

Variable Name	Variable Label	Type	Length
STUDYID	Study Identifier	Char	12
USUBJID	Unique Subject ID	Char	40
AGE	Age	Num	8
…more rows…

Sheet name = 2-letter domain (DM, AE, VS…) or SUPP*

Column titled Variable Name lists the variables

Sheets named Codelists, Overview, Cover are skipped

SDTM & ADaM domain codes both supported
