Support

viewparquet runs entirely in your browser. Most issues relate to file size, browser memory, or SQL syntax. Check the FAQ on the home page first.

Contact

The fastest path is the support widget in the bottom-right corner of the data viewer. It opens a messenger so replies are waiting for you when you come back.

You can also email us at antony@kaladev.co with a description of the problem, your browser, and file type (Parquet, GeoParquet, CSV, or JSON). Please do not attach sensitive datasets unless you have permission to share them.

S3 & remote URLs

Open Parquet and other formats from HTTPS links, public s3:// objects, or private buckets in the viewer via Open from S3 / URL (or /viewer?open=remote).

  • Public URL: paste HTTPS or a presigned link; no credentials needed.
  • Private bucket: use the Credentials tab with AWS, Cloudflare R2, GCS (HMAC), or MinIO presets. Keys sign requests in-browser only.
  • 403 / CORS errors: check bucket policy and IAM permissions; for browser HTTPS URLs the bucket may need CORS on GET.

AI assistant

The AI assistant is optional. A ViewParquet Cloud plan includes managed AI with no provider account or API key. Advanced users can instead add their own OpenRouter or supported direct-provider key under Settings → AI → Connection.

  • Managed Cloud AI: sign in and choose a Cloud plan. DeepSeek V4 Flash is the default, and the chat model picker can search the live tool-capable OpenRouter catalogue. Provider credentials remain on the ViewParquet server.
  • BYOK setup: create a key at openrouter.ai/keys and paste it in Settings → AI → Connection. Pick a model in the chat panel or Models settings.
  • Data sharing: control what the assistant sees in Settings → AI → Privacy (column headers, types, metadata, sample values). Chat and SQL helper can use different presets.
  • SQL Ask AI / Fix: use ⌘K or Ctrl+K in the SQL editor. It follows your selected BYOK model and your data-sharing settings.
  • Usage and billing: AI usage and charges use your plan allowance in managed mode and your provider account in BYOK mode. Current managed allowance usage appears in Settings → AI.

For what leaves your browser when AI is enabled, see our Privacy Policy.
