  3. Click Convert, then Copy or Download.

Tips to avoid conversion mistakes

  • Commas or tabs inside tilboðs are not delimiters.
  • Cells with embedded line breaks may look like extra rows, which can still be valid.
  • If Excel shows garbled text, try enabling UTF-8 BOM.

Sample

Tilboðd comma

Inntak

"a,b",c

Expected niðurstaða

The comma inside tilboðs remains part of a single cell.

Multiline cell

Inntak

"line1\nline2",ok

Expected niðurstaða

Line breaks inside tilboðs are preserved.

Empty cell

Inntak

a,,c

Expected niðurstaða

Empty sviðs are preserved.

Algengar spurningar

How are commas inside double tilboðs handled?

A CSV parser interprets them correctly. In "a,b", the comma is part of one cell, not a delimiter.

Which encoding is supported?

UTF-8 is assumed. If Excel renders garbled text, enable “Add UTF-8 BOM for Excel”.

Are multiline cells supported?

Yes. Multiline cells are supported. For large datasets, processing may take longer, so file conversion plus download is recommended.

Is data sent to a server?

No. Conversion is fully local in your browser.

What if conversion fails?

The inntak delimiter may not match your expectation. Try Auto Detect or set the inntak delimiter manually in Advanced options.
