Frequently Asked Questions
A Markdown Table Formatter is an online developer utility that takes raw, unaligned, or malformed Markdown tables and formats them into clean, perfectly padded GitHub Flavored Markdown (GFM) tables. It normalizes column widths, header separators, and alignment markers.
When copying tables from documentation, PDFs, or AI output, markdown tables often lack proper header delimiter rows (|---|---|), have uneven cell counts across rows, or miss leading/trailing pipe characters. ToolZeno's auto-repair engine detects structural anomalies and automatically injects delimiters, pads missing cells, and escapes pipe characters.
Pretty Alignment pads every cell in a column with whitespace so that all vertical pipe characters (|) align neatly in visual plain-text source files. Compact mode removes extra cell padding to minimize string size while preserving GFM rendering syntax.
Yes! You can paste raw Comma-Separated Values (CSV) or Tab-Separated Values (TSV) from Excel or Google Sheets, or upload .csv files directly into the formatter to generate formatted Markdown tables instantly.
Yes. ToolZeno executes all Markdown parsing, table alignment, syntax validation, and repair algorithms 100% client-side in your web browser. No document content or uploaded files are ever sent to any external server.
