What Excel is

An Excel workbook is a zip archive of XML parts describing sheets, cells, formulas, styles and charts. The .xlsx extension is that format; .xls is the older binary one from before 2007.

Finance, operations and anyone who received a file from finance or operations.

What BBCode is

BBCode uses square-bracket tags. Table support is not universal, but table, tr, th and td are widely implemented.

phpBB, vBulletin and forum software descended from them.

What changes when you convert Excel to BBCode

Only the first sheet is read, and cells are read as the text Excel displays rather than the number underneath. That matters for dates: a cell showing 15/03/2026 arrives as that string, not as a serial number you would then have to decode.

Check that your forum has table tags enabled. Many boards ship with them switched off.

What carries over from Excel to BBCode

Excel records 5 things about a table that BBCode has no way to hold.

Excel distinguishes a number from the text of a number; BBCode does not, so every value arrives as text and has to be re-parsed by whatever reads it next.

An empty cell and a missing one are the same thing in BBCode, so a null and an empty string in the Excel both come out blank and can no longer be told apart.

A line break inside a cell ends the row in BBCode, so line breaks are replaced rather than carried through.

Anything visual in the Excel - weight, alignment, colour, column widths - has no counterpart in BBCode and is dropped. The values are what survives.

BBCode is the end of the line for this data. Reading the table back out of it is a separate and much harder problem than writing it, so keep the Excel if you will need the values again.

A worked example

Three rows of staff data, with an identifier that has a leading zero, a value containing a comma, a value containing quotes and one blank cell. Those are the four places formats disagree, so they are the four places to look.

Questions

How do I convert Excel to BBCode?

Paste your Excel into the box above or drop the file onto it. Check the table in the grid, then copy or download the BBCode from the output panel. It takes one step and the data never leaves your browser.

Does converting to Excel keep my formulas?

No. A table has values, not formulas. If your source came from Excel in the first place, the formulas were already resolved to their results before they reached this page. Anything that was =SUM(A1:A10) arrives as the number it produced.

Can I convert the BBCode back to Excel afterwards?

Not mechanically. BBCode keeps how the table looks, not what it held, so going back means reading the values off the page again. Keep the Excel if you will need it.

Will my numbers still be numbers?

They will read the same, but BBCode stores them as text. Anything that sorts or sums the result will need to parse them first, and a leading zero or a currency symbol is the usual place that goes wrong.

One of my cells has a line break in it - what happens?

A line break would end the row in BBCode, so it is replaced instead of carried through. The rest of the cell stays where it belongs.

Is there a limit on file size?

No. The work happens on your own machine, so the limit is your machine's memory rather than an upload cap. A file with tens of thousands of rows converts in a second or two.

Is my data uploaded anywhere?

No. The parsing and generating are done by JavaScript running on this page. You can watch the network tab while you convert and see that nothing is sent.
