Bulk upload

Bulk upload on a bookmark’s run page runs every record of a CSV or XLSX file through the form, one at a time, and adds each result to the session. Nothing is saved until you save the entries, so you can check them first.

The file

A .csv file, or an .xlsx file whose first sheet holds the records.
One header row, then up to 10,000 records.
An optional first column name with the name of each run. Without it, runs are named bulk-upload-<id>-1, -2, and so on.
One column per model input, named after the feature the field maps to. A onehot-category field takes one column per option, holding 1 for the chosen option and 0 for the others. For a model that takes features by position, the field’s label also works.

Every model input must be present, headers must be unique, and no other columns are allowed.

name,age,income,has_guarantor,employment__salaried,employment__self_employed,employment__unemployed
batch-applicant-01,52,61000,false,1,0,0
batch-applicant-02,24,18500,true,0,1,0

How values are read

Field kind	Write
`number`, `rating`	A finite number.
`boolean`	`true`, `1`, `yes` or `si`; `false`, `0` or `no`.
`multi-choice`	Values separated by `;`.
`series`	A JSON array.
Other kinds	The text value, or JSON.

Run and check

Choose Bulk upload and pick the file. The button shows the progress (“Bulk 12/40”) and turns into Stop while it runs; when it ends it summarizes the outcome, for example “38 uploaded, 1 failed, 1 skipped”. Then save the session entries you want to keep.

A problem with the file as a whole refuses it before anything runs:

Message	Cause
Missing input columns: …	A model input has no column.
Unknown input columns: …	A column matches no model input.
Headers must be unique	Two columns share a name.
File exceeds maximum of 10000 records	Too many rows.
Unsupported file type	Not a CSV or XLSX file.

A problem with one record skips that record and the others still run: a missing required value, a number that is not finite, a boolean that is not one of the words above, or invalid JSON. The first five skipped lines are reported by line number.
