CSV To HTML Table: A Spreadsheet As A Web Page

This tool takes a CSV or Excel export and gives you the HTML for it — but the conversion is the easy half. The output is the point. Switch on sortable columns and the generated code carries about thirty lines of plain JavaScript that sort a column when its header is clicked, numerically where the column holds numbers. Switch on the search box and rows that do not match what is typed are hidden, with a live count. A sticky header keeps the column names in view down a long table. None of it needs a library, a framework or a build step: it is a <style> block, a <table> and a <script> you can read.

Who It Is For

Anyone holding a file they did not write. A shop owner with a stock list, a treasurer with a fixtures table, a teacher with a results export, someone whose data came out of a chat with an assistant and now has to go on a page today. You do not need to know what a <thead> is. If you want to build a small table by hand instead, the HTML Table Generator is the tool with the grid in it; if you want the data rather than the markup, CSV to JSON converts the same file the other way.

How It Works

Everything runs in your browser. The file is read, parsed and turned into markup on your own machine, and nothing is sent anywhere unless you press Publish. The parser handles the cases that break a simple split-on-comma: a quoted field may contain commas, line breaks and doubled quotes; records may end with Windows, Unix or old Mac line endings; and the invisible byte order mark Excel writes at the start of a UTF-8 file is removed before it can corrupt the first column name. Every value is escaped on the way into the HTML, so a cell containing a tag stays text.

Columns, Numbers And Phones

Alignment is inferred per column: numbers go right, text goes left. A column of leading-zero identifiers is deliberately kept as text, because 0042 is a SKU and sorting it as a number puts it next to 42. In the Columns strip you can rename a heading, leave a column out, change its alignment, or set its type yourself — and changing the type never rewrites a cell, it only tells the sort what to do. The phone question gets a real answer too: horizontal scroll keeps the grid intact and is right up to about five columns, while the stacked card layout turns each row into a labelled block using the header names, which is what a wide table needs on a small screen.

Limits

A dropped file stops at 5 MB, because the whole conversion happens in one browser tab. The preview shows the first 200 rows; the code always holds every row. There are no merged cells, no formulas, no cell colours from the spreadsheet and no charts — a CSV does not contain any of those. Excel users export to CSV first; the .xlsx file itself is not read here.

Then Put It Online

A table is usually needed by someone else, today. Publish wraps your table in a complete page and puts it on a free OxyPages link with HTTPS in seconds, with no account. The link lasts 30 minutes unless you claim it, claiming is free, and from there you can pick your own address and connect a custom domain on a paid plan. See how it works.
