GridSail — Web Tables to Excel

Save web tables to Excel with protected IDs. Combine pages, use 3 filters and hide empty columns. Free, local, no account.

GridSail turns tables already displayed on a webpage into a clean spreadsheet, locally and without an account. NEW IN 0.5.0 • Combine up to three column conditions; all must match (AND) • Find a column name without scrolling through a long list • Select all columns or hide fully empty selected columns with one click • Empty-column checks use every captured row, including rows outside the current page or filter • Clear global search while keeping column conditions IN 0.4.0 • Filter numeric values with ≥, ≤ or inclusive ranges using an explicit decimal convention • Click a preview header to cycle ascending, descending and original order • Browse every output row in 100-row preview pages; export includes all matching pages • Locate and skip rows beyond the first preview page IN 0.3.1 • Temporarily skip individual output rows and restore them without deleting raw data • Amber highlights identify numeric Excel text fallbacks; filter to review these rows before export • Does not contain column filter, with empty criteria inactive • Preview limit remains visible even when duplicates are removed ALSO INCLUDED IN 0.3 • Filter a chosen column: contains, case-sensitive equals or not empty • Sort output rows by natural text or explicit dot/comma decimal formats • Skip repeated full-header rows without deleting the captured source • Choose real Excel numeric columns for calculations; identifiers remain protected ALSO INCLUDED • A persistent Chrome side panel: browse the webpage while keeping the workspace open • Read & add page reads the latest webpage before merging, so you can navigate then collect with one click • Remember selected columns, exported names, column order, deduplication settings and filename for a website • Filter visible-column content; the same filtered rows are exported • Deduplicate by whole row or a selected key such as SKU; conflicting values are flagged and the first row is kept • Align uniquely matching column headers when source order changes • Export real Excel .xlsx, CSV, Markdown or JSON, or copy tab-separated text • Undo the latest collection change, including Clear EXCEL THAT KEEPS IDENTIFIERS Excel defaults to literal text, keeping leading zeros, long IDs and formula-like content intact. Choose Number (.) for 1,234.50 or Number (,) for 1.234,50 on price/quantity columns. Recognized values become numeric Excel cells. Leading-zero IDs, values beyond 15 significant digits, formulas, dates, percentages and unrecognized formats remain text; a fallback count is shown. Currency symbols are accepted; currency display formatting is not retained. Check mixed formats against the selected convention. Numeric types affect Excel only. Files include frozen headings and filters. CSV/clipboard formula-like values receive an apostrophe prefix; spreadsheet software may still auto-format CSV identifiers. A SHORT WORKFLOW 1. Open a webpage with a table and click the GridSail toolbar icon 2. Choose the table, keep useful columns and export 3. For more pages, click Read & add page, navigate the webpage, then click Read & add page again. No need to close the side panel or refresh first 4. Use Columns & layout to rename/reorder columns and remember the layout Filters affect preview and export only. Read & add page collects all captured source rows and skips exact full-row duplicates. Blank deduplication keys fall back to whole-row comparison. Turn deduplication off to inspect conflicting captured rows. FREE LOCAL FEATURES All features in this version are free, including saved layouts and all export formats. No account, subscription, checkout or paid-locked features. LOCAL DATA, LIMITED ACCESS Reads rendered HTML and ARIA tables in the current main webpage only when invoked through the toolbar, Refresh or Read & add page. The sidePanel permission displays the workspace; it does not add persistent access to websites. On a new site or tab, click the toolbar icon again if page access is unavailable. Table content, page title and source origin are processed locally. Collections, source origin, one Undo record and preferences remain in local browser storage. Page snapshots and search filters remain in panel memory. Saved layouts can include Excel types, sorting and header cleanup, but never filter text, row skips or numeric-review state or preview page. Up to 20 saved layouts and 200 KB of preferences. No table uploads, analytics SDKs, remote code, password-field access, cookies or browser-history access. No automatic background browsing. CLEAR LIMITS No image/PDF OCR, canvas tables, embedded frames, automatic pagination or hidden-row recovery. Virtualized tables include only rendered rows. Capture is bounded to 30 candidate tables, 100,000 cells, 10,000 rows and 100 columns; known truncation is shown. A collection supports up to 10,000 rows and 4 MB. Preview shows 100 output rows per page; export includes all matching rows within these limits. Existing 0.1.0 and 0.2.0 collections remain readable. Failed or stale writes do not replace a newer stored collection. Chrome 116 or later is required. Screenshots show the explicitly labeled interactive demo with sample data. The website demo does not exercise native Chrome permissions or the actual browser side panel.

Use preview paging or filtering to locate any output row. Skips apply after deduplication, before output sorting, and remain temporary for the current dataset view. Refreshing the page snapshot, collecting or switching datasets resets skips. Restore skipped rows or Reset filters & tidy recovers them. Review text fallbacks filters both preview AND export to those rows; Show all rows exits it. Numeric filter bounds follow the selected dot/comma decimal convention. Blank or unrecognized source values are excluded and counted. Invalid or reversed bounds disable export until corrected. Numeric filters do not change source values or Excel column types. Header sorting follows the selected Excel column type; text is the default. COMPOUND FILTERS Add up to two extra conditions in Filter & tidy. Every active condition must match. Invalid numeric bounds in any condition pause export. Removing a condition broadens results; Reset filters & tidy clears all conditions. Filter values and the column-name finder are not saved in layouts. Column-name search only locates controls and never hides exported columns. Hide empty columns affects selected columns only, checks the entire captured source, and leaves source data unchanged. Select all columns can restore hidden columns.
