# CSV
CSV (Comma-Separated Values) is a popular file format used for storing and exchanging tabular data.
CSV settings
You can fine-tune importing data from a CSV file with the following options:
### Encoding
Specify the file encoding as one of:
* UTF-8
* UTF-16
* Win-1250
* Win-1251
* Win-1252
* Win-1253
The default encoding is UTF-8.
### First row is a header
This checkbox option indicates whether the first row of the CSV file contains column names.
When checked, the app will treat the first row as headers, enabling you to map the data columns to their corresponding fields based on these names.
When unchecked, the app will interpret all rows as data. You'll need to reference particular columns by uppercase letters A, B, C, D, E, and so on.
### **Ignore inconsistent number of columns**
This checkbox allows you to instruct the app to ignore rows in the CSV file that do not have the same number of columns as the header row. This can be useful if some rows have missing or extra data.
### Start from line
This field allows users to specify the line number from which the app should start processing the CSV file. The default value is "1", which means processing will begin from the first line of the file.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://help.stockeo.solvenium.com/data-mapping/format/csv.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
