Connect Data
Upload Files
Upload a flat file directly as a data source. NNIPA reads its structure, profiles it, and adds it to the Catalog — the same as any other connector.
Quick Start
- 1
Pick a connector
Under Files, choose the format your data is in — CSV, Excel, JSON, JSON Lines, Parquet, or Avro.
- 2
Configure the source
Give it a Source Name and, optionally, a Description. The File Format is preconfigured from the connector you picked — click "Change" to switch it.
- 3
Upload the file
Choose the actual file from your computer and confirm it parses correctly.
- 4
Test & save
NNIPA validates the file before saving it as a source.
- 5
Let it profile itself
Saving kicks off analysis automatically — the file is profiled and added to the Catalog with no further action from you.
Supported formats
CSV
Comma-separated values — the most common flat format.
Excel
Reads the first sheet of a .xlsx workbook by default.
JSON
A single JSON document or array. Nested structures are flattened during profiling.
JSON Lines
One JSON object per line — a good fit for large exports and logs.
Parquet
Columnar binary format that preserves schema and types natively.
Avro
Row-based binary format with an embedded schema, common in streaming pipelines.
- File uploads are one-time snapshots — they don't refresh on their own.
- If your data changes regularly, use Connect Database or CDC instead so NNIPA can keep it current automatically.
- Description is optional but helps others in your workspace understand the source at a glance.
