Table conversion guide
How do you convert Excel or CSV to Markdown?
Markdown tables are easier to edit and reuse than screenshots when moving spreadsheet data into README files, Notion, Obsidian, documentation, or AI prompts.
The quickest method
- Open the Excel / CSV to Markdown tool;
- Choose an
.xlsx,.xls, or.csvfile; - Select the worksheet when the workbook contains several sheets;
- Copy the Markdown or download a
.mdfile.
The file is read locally in your browser and is not uploaded to an Aixuno application server.
Prepare the spreadsheet
- Use short, unique column names in the first row;
- Remove empty rows and columns used only for visual spacing;
- Avoid merged cells, which Markdown tables do not support;
- Confirm formula results before conversion;
- Split extremely wide tables into smaller focused tables.
Why are pipe characters escaped?
Markdown uses | to separate cells. When a cell contains its own pipe, the converter adds a backslash so the table structure remains valid.
How do you fix CSV encoding?
Export the source as “CSV UTF-8” from Excel or another spreadsheet application. The downloaded Markdown file also uses UTF-8.
Where can you use the result?
The generated table works well in GitHub README files, technical documentation, Notion, Obsidian, knowledge bases, and AI workflows. For very large tables, keep only the rows and columns needed for the task.
