Stop your AI scrambling the numbers in a CSV export

Your AI reads rows and columns instead of a wall of commas. A raw CSV is where models lose track of which value belongs to which column. As a Markdown table every cell sits under its header, so audits and comparisons come back with the numbers in the right place.

Convert a CSV file

Three free, no account, nothing stored.

What you get

The header row as the table header.
Every row as a table row, in order.
Character encoding detected, so accented names don't turn to noise.

Before you drop it in

Comma-separated only. If your export uses semicolons, open it in Excel and save as CSV UTF-8 first.
Big exports make big tables. The meter shows the token count before you paste.

What survives, what doesn't

Header row and values	✓ Kept
Row order	✓ Kept
Quoted fields with commas inside	✓ Kept
Very wide files	△ Partly	Fifty columns makes a fifty-column table. Drop the columns you don't need first.

What it looks like

A stock list converts to:

| item | qty | location |
| --- | --- | --- |
| bolts M12 | 120 | Bay 3 |
| nuts M12 | 96 | Bay 3 |
| washers | 400 | Bay 1 |

Questions about CSV

Does it handle semicolon-separated files?

Not directly. Open in Excel, save as CSV UTF-8, then convert.

What about accented characters?

Encoding is detected automatically. If a file still looks wrong, save it as UTF-8 and try again.

Is there a row limit?

Only the 100 MB file limit. Watch the meter on very large files.
