About Data Preview
Data Preview helps people and software agents prepare CSV and flat JSON records for a defined import specification.
A Clear Path from File to Import
Recognize headers, review column mappings, analyze data quality, and approve missing work-email domain repairs. Download accepted rows, rejected rows, structured exceptions, and a transformation log.
Your Organization’s Workspace
Supabase verifies sign-in. Neon stores organizations, memberships, versioned templates, and job summaries. Server checks and database row-level policies restrict organization data to its members.
File Handling
Background-job source and result files are stored privately for up to 24 hours, then purged. File contents are not saved in Neon job history. History stores counts, status, template name/version, creator ID, and timestamps. Download the files you need before clearing your workspace.
Current Limits
CSV, flat JSON and XLSX workbooks are supported. Current deployment capacity is 10 MB and 50,000 rows per file; organization owners can set lower limits. Customer-provided destination specifications can be uploaded, edited and versioned. Background-job files expire after 24 hours. Authenticated MCP tools and Stripe checkout integration are included; live billing requires account credentials, a configured price and webhook. Vendor certification and regulatory compliance require separate review.
