A spreadsheet grid that emits GFM tables

Add rows and columns, type cells, and copy a pipe table with a header separator (`| --- |`). Alignment colons can be added if the UI exposes them. Cell count is capped so a 400-cell grid cannot freeze the tab.

READMEs, RFCs, and changelog matrices

Faster than hand-typing pipes when comparing feature flags or browser support. CSV to JSON is the path if the source of truth is a spreadsheet file. HTML to Markdown can import an existing `

` with mixed success.

Pipes inside cells and wide tables

A `|` inside a cell breaks GFM unless escaped. Very wide tables overflow on mobile GitHub—split columns. Generation is local; there is no Google Sheets login.

Frequently asked questions

Does it support merged cells?

Standard GitHub tables do not merge cells. Keep one value per cell or split the topic across rows.

Can I paste from Excel?

Paste into cells or convert TSV via Find and Replace if tabs become columns. There is no `.xlsx` parser on this page.

Why is there a row of dashes?

GFM requires a separator row after the header. Do not delete it or GitHub will not render a table.
