Import from File
Import an existing collection of tests directly from a CSV, Excel, JSON, or JSONL file to create a new test set in seconds.

Supported Formats
| Format | Extension | Best for |
|---|---|---|
| CSV | .csv | Single-turn tests in a spreadsheet |
| Excel | .xlsx, .xls | Single-turn tests in a spreadsheet |
| JSON | .json | Nested or flat test data |
| JSONL | .jsonl | Large datasets — one test object per line |
Files up to 10 MB are accepted.
How It Works
The import flow is a guided three-step process: Upload & Map, Inspect Data, and Import.
Step 1 — Upload & Map
- Open the Test Sets page . In the toolbar above the test sets grid, click the Import button and select Import from File.
- Select the Test Type that matches your data before uploading:
- Single-Turn — tests with a single prompt/response exchange.
- Multi-Turn — tests that drive a multi-turn conversation; no prompt field required.
- Drag and drop your file onto the upload area, or click to browse.
Once the file is uploaded, Rhesis analyses its structure and proposes a column mapping — a table that links each column in your file to a Rhesis test field.
Select the correct Test Type before uploading your file. The available mapping fields and validation rules differ between Single-Turn and Multi-Turn, and the type cannot be changed after the file has been analysed.
Single-Turn Fields
Each row should have a prompt_content, category, topic, and behavior. The remaining fields are optional.
| Rhesis Field | Required | Description |
|---|---|---|
prompt_content | Yes | The test prompt sent to the AI system |
category | Yes | High-level category of the test |
topic | Yes | Topic within the category |
behavior | Yes | The specific behavior being evaluated |
expected_response | No | Expected output used to evaluate the response |
language_code | No | BCP-47 language code (e.g. en, de, fr) |
Multi-Turn Fields
Multi-turn tests do not require a prompt field — the conversation is driven by the test configuration. Each row should have category, topic, and behavior, plus the conversation fields below.
| Rhesis Field | Required | Description |
|---|---|---|
category | Yes | High-level category of the test |
topic | Yes | Topic within the category |
behavior | Yes | The specific behavior being evaluated |
goal | Yes | The objective of the conversation test |
instructions | No | How the test agent should conduct the test |
restrictions | No | Forbidden behaviors for the target system |
scenario | No | Contextual framing for the test |
language_code | No | BCP-47 language code (e.g. en, de, fr) |
These fields can be provided in a flat format — as individual columns in CSV/Excel or top-level keys in JSON/JSONL — or nested inside a test_configuration object. Both layouts are recognised automatically.
Columns mapped to (skip) are ignored during import.
If an LLM is configured for your organization, an AI mapping button appears next to the confidence score. Click it to let the AI re-map columns based on their names and sample values.
Confidence Score
Rhesis rates its mapping confidence as a percentage. When confidence reaches 100%, the dialog advances to the next step automatically. For lower confidence scores, review the suggested mapping before continuing.
Step 2 — Inspect Data

Before committing the import, review a paginated preview of how your data will be parsed.
A validation summary at the top of the preview shows:
- Valid rows that will be imported
- Warnings — rows that will import but may have missing optional fields
- Errors — rows that will be excluded from the import
Each row in the preview grid shows a status icon:
| Icon | Meaning |
|---|---|
| Green check | Row is valid |
| Amber warning | Row has a warning; hover to read the message |
| Red error | Row has an error and will be excluded; hover to read the message |
Use the Back button to return to Step 1 and adjust the column mapping if the data does not look right.
Step 3 — Import
Set a name and optional description for the new test set, then click Import.
The summary shows how many rows will be imported. Rows with errors are automatically excluded — only valid rows are written to the test set.
The test set name defaults to Import: <filename>. Change it to something
descriptive before confirming.
Once the import completes, the new test set appears in the Test Sets page and you can execute it immediately.
