What does Crawl extract?

Crawl fetches the public URL you submit and extracts HTML tables, JSON-LD blocks, and qualifying lists into reviewable rows.

What does Chart accept?

Chart reads .xlsx and .xls files in the browser and can also chart the first dataset sent from Crawl.

Will Crawl work on every page?

No. Pages behind logins, heavy bot protection, or unusually large responses may fail or return no structured data.

Chart files stay in your browser. Crawl requests are processed on demand from the URL you submit so the service can fetch and parse the page.

Smart CSV Import with Auto-Detect Delimiters and Encoding

Smart CSV Import Is Here

Starting 2026-07-29, DataVizForge includes a smart CSV import engine that automatically detects delimiters (comma, semicolon, tab, pipe), character encoding (UTF-8, Latin-1, Shift-JIS), and whether the first row is a header. No more manual configuration — just upload your CSV and start charting.

How It Works

Upload — Drop your CSV file onto the chart page
Auto-detect — The engine scans the first 100 rows to identify delimiter, encoding, and structure
Preview — A preview table shows the parsed data with detected column types
Adjust if needed — Override any detection with the manual settings panel
Chart — Select your axes and render the chart instantly

Supported Formats

Delimiters — Comma, semicolon, tab, pipe, custom
Encodings — UTF-8, UTF-16, Latin-1, Shift-JIS, EUC-JP, GB2312
Line endings — Unix (LF), Windows (CRLF), old Mac (CR)
Quoting — Standard CSV quoting with escaped quotes

Why This Helps

CSV files from different regions and tools use different conventions. European spreadsheets often use semicolons instead of commas. Japanese data files may use Shift-JIS encoding. Our auto-detect handles all of these cases automatically, saving you time and preventing garbled characters.

The smart import is available now for all users. Visit datavizforge.com to try it.
