Excel → Web Table Auto Fill

Automatically fill web table cells row by row with data from Excel spreadsheets

Excel → Web Table Auto Fill Note: The control window only appears after clicking the Chrome extension icon on a page that has a web table. Tired of copying and pasting Excel data into web tables one cell at a time? This Chrome extension automates the process — load your Excel file, select the web cells, and fill them row by row with a single click. Built for repetitive web-form entry such as ERP document drafting, inventory entry, and bulk submissions. [How to Use] 1. Click the extension icon to open the floating panel on any web page. 2. Click "Choose file..." and select your Excel file (.xlsx, .xls, .xlsm). 3. (Optional) Pick a sheet from the Sheet drop-down for multi-sheet workbooks. 4. Set the Start Position with a single Excel cell reference (e.g. B2, L4). Lowercase is auto-uppercased; invalid input is highlighted. 5. (Optional) Tick "Skip hidden rows/cols" to ignore Excel-hidden rows/columns during fill. 6. Click "Start Selection", then click the web table cells in the order you want them filled. Cells in the same <tr> get numbered orange badges. 7. Click "Fill Data Once" — the current Excel row is written into the selected cells, and both the Excel row pointer and the web cursor advance to the next row automatically. 8. Repeat "Fill Data Once" for each row, or use "Clear Selection" to start over on a new <tr>. 9. Edited the Excel file in the meantime? Click the ↻ button next to the file name to reload from disk — no need to re-pick. [Features] - Supports .xlsx, .xls, .xlsm via SheetJS, parsed locally (no network upload). - Sheet selector — works on multi-sheet workbooks; hidden sheets are labelled (hidden). - Single-input Start Position — type a cell reference like B2 or L4 instead of separate row/column boxes. - Skip hidden rows/cols — honors Excel's hidden metadata for clean data fills. - Horizontal merge handling — merged cells like L4:M4 act as one logical column. - File reload (↻) — re-reads the file via File System Access API, surviving Excel's atomic save. - Numbered badges show selection order; status bar reports source sheet and row after each fill. - Draggable floating panel; state is preserved when hidden. - Works on any website with HTML table cells — no domain restrictions. [Publisher] ArirangClaw — see more tools at https://arirangclaw-tools.pages.dev/ What's new in 1.3.0 ■ It now tells you why nothing happened - On a page with no table, the panel says so and dims Selection / Fill instead of staying silent. If a table loads later, it re-enables itself. - On pages where Chrome blocks extensions (chrome:// pages, the Chrome Web Store, the PDF viewer), the toolbar icon shows a red "!" with the reason. This is what most new users ran into right after installing. - Clicking somewhere that isn't a data cell during selection now explains why, including header cells. ■ Now works on forms with input boxes and dropdowns - Previously the tool replaced the entire cell, which deleted the site's own input box or dropdown. The value looked filled in, but the form saved a blank. It now writes into the control itself, so the page actually receives the value. - If a value doesn't fit — text into a number box, or a dropdown with no matching option — that cell is skipped instead of being broken, and the result tells you. ■ Fixes for data landing in the wrong place, silently - Reaching the last row of a table used to report success, then overwrite that same row on the next fill. It now stops and says so. - Tables with merged (rowspan) cells shifted every Excel column by one with no warning. Filling now follows the visual columns correctly. - Tables that put each row in its own section stopped advancing after the first row. They now continue properly. ■ Other improvements - Selection numbers stay on the correct cells when you scroll. - Fill results show how many cells were written (e.g. "3/4") and turn red when nothing was. - Closing the panel no longer leaves orange outlines on the page. - The toolbar icon works right after an extension update, with no page reload needed. - Publisher name is now ArirangClaw (same developer). - Added an optional "Buy me a coffee" link in the panel footer. Everything stays free — no feature is locked behind it.
