How to Export All Tables From a Webpage at Once (Batch Guide)

You're looking at a data portal with 8, 12, maybe 20 tables on one page — quarterly reports, regional breakdowns, year-over-year comparisons. Copying them one by one is tedious. Forgetting one means going back. And if they have merged cells, each copy-paste needs manual fixing.

There's a faster way: detect every table automatically and export them all in one click.

The Problem With One-by-One Export

When a page has multiple tables, the manual approach falls apart:

• Selection is fragile — dragging across a large table often misses the last row or includes surrounding text;
• You lose track — "Did I already copy Table 7?" becomes a real question when there are 15 tables;
• Formatting breaks differently each time — merged cells, different column counts, varying header structures mean every table needs its own cleanup;
• Time multiplies — 3 minutes per table × 12 tables = 36 minutes of pure drudgery.

How TableGrab's Batch Export Works

VKT TableGrab scans the entire page in one pass and lists every valid HTML table it finds. Here's the workflow:

1. Click the TableGrab icon on any page with tables;
2. All tables are auto-detected, showing row × column counts (e.g., "24 rows × 6 cols");
3. Hover over any table in the list — it highlights the corresponding table on the page with a blue outline;
4. Check the tables you want, or use Export All for everything;
5. Each table downloads as a separate CSV file with a smart filename: PageTitle_table3_2026-08-28.csv.

Why separate files? Because concatenating tables with different column structures into one CSV produces invalid data. Separate files keep each table clean and immediately importable.

What Gets Detected (and What Doesn't)

TableGrab uses smart filtering to show only real data tables:

• Detected — standard <table> elements with 2+ columns or 2+ rows of data;
• Filtered out — layout tables (1×1), hidden tables (display: none), and empty tables;
• Shadow DOM — tables inside open shadow roots are found and parsed;
• Not supported — CSS Grid/Flex layouts that look like tables but aren't <table> elements, Canvas-rendered tables, and tables inside cross-origin iframes.

Toggle Include hidden tables in settings if you need tables that are normally invisible (e.g., collapsed accordion content).

Real-World Use Cases

Tips for Large Exports

• Check the row counts first — a table with 10,000 rows will take a moment; TableGrab caps at 20,000 rows per table for safety;
• Use "Export Selected" — if you only need 3 of 15 tables, don't export all 15;
• Truncated indicator — if a table shows a "+" after the row count, it was partially captured due to size. Export that table individually for the full data;
• Filename convention — files are named PageTitle_tableN_timestamp.csv so you can sort and identify them easily.
