Can the formatter handle nested tables?

Yes. Nested tables (a table inside a td element) are correctly indented to show both the outer and inner table hierarchy.

Should I use HTML tables for page layout?

No. HTML tables should be used only for tabular data. Use CSS Grid or Flexbox for page layout — they are more accessible and easier to maintain.

Format HTML Table Code Online

HTML tables have deep nesting — table, thead, tbody, tr, th, td — that becomes completely unreadable without proper indentation. FixTools formats your table markup so every row and cell is clearly structured and easy to edit.

How to use this tool

💡

Paste your HTML table markup and format. Every level of table nesting — from table to tr to td — will be properly indented and easy to read.

How It Works

Step-by-step guide to format html table code online:

1
Paste your table HTML
Paste the full table HTML, including the opening and closing <table> tags.
2
Format
Click Format to apply correct indentation to every level of the table structure.
3
Inspect rows and cells
Scan the formatted output to verify rows, headers, and data cells are correctly structured.
4
Edit and re-format
Make any necessary corrections and format again to confirm the structure.

Real-world examples

Common situations where this approach makes a real difference:

Debugging a broken HTML table layout

A table renders with misaligned columns. Formatting the HTML reveals a missing closing </td> or an extra </tr> that is causing the layout to break.

Editing a data table exported from Excel or Google Sheets

HTML exported from spreadsheet tools is compressed and difficult to edit. Formatting it first lets you identify and modify specific rows, columns, and cells.

When to use this guide

Use this when editing or debugging HTML tables where the row and cell structure is hard to follow because of missing indentation.

Pro tips

Get better results with these expert suggestions:

Count columns by scanning td elements

After formatting, count the td elements in each tr to verify that all rows have the same number of columns. Mismatched columns cause broken table layouts.

Validate colspan and rowspan

After formatting complex tables with colspan or rowspan attributes, validate the HTML to ensure your spanning declarations are correct.

Consider semantic alternatives

If your HTML table is being used for layout (not data), consider replacing it with CSS Grid or Flexbox. Formatting the table first makes the structure visible and easier to migrate.
