CSV guide

Explore a CSV locally and see what’s inside.

Inspect rows, columns, missing values, and patterns in your browser before you import an unfamiliar CSV elsewhere.

Open a CSV Your file stays in your browser.

What you can see

Open the file in Unwrap to get a quick overview. You can read one record at a time, compare rows in a table, and check the detected columns and file settings.

Start with a few rows

Imagine an export that begins like this:

order_id,customer,total,status
1042,Ada,49.90,paid
1043,Grace,,pending
1044,Linus,19.00,paid

The empty total stands out straight away. You can also check whether Unwrap recognized order_id as an identifier and which values appear in status. The CSV itself remains unchanged.

Choose the view that helps

01

Cards

Read one record at a time. This is useful when the CSV has many columns.

02

Table

Compare rows and scan values in the familiar column layout.

03

Structure

Check detected columns, common values, missing values, and file settings.

What to check first

  1. Start with the column names and first rows. Make sure you opened the file you expected and that the data is split into the right columns.
  2. Look for missing or unusual values. Check whether anything stands out or looks wrong.
  3. Check the file settings. The Structure view shows the delimiter, encoding, line endings, and quote character.

After that, you should know whether the CSV is ready to use, needs more investigation, or should be exported again from the original system.

When you need more than the first results

For a large CSV, Unwrap may begin with a sample. If you need counts or column details for every row, select Load full file. Unwrap is read-only: your original CSV stays unchanged, and any edits belong in the tool you use next.
