CSV File Requirements

Do not use a thousands separator in your data.

Supported Date Formats

The following date formats support the two-digit format of the year:

That is, 18-08-14 and 18-08-2014 are interchangeable and will both work.

If you use the two-digit year format, consider the following:

The values from 00 to 68 inclusive refer to the years from 2000 to 2068 correspondingly.
The values from 69 to 99 inclusive refer to the years from 1969 to 1999 correspondingly.

Let’s look at some specific cases:

If you use the yy-mm-dd format, the date 66-12-12 will not be accepted: according to the rules, it refers to the year of 2066, and 2066 is outside of the allowed range (which is, between 1900 and 2050 inclusive).
If you use the yymmdd format, the date 661212 will not be accepted as a date for the same reason as in the previous case. Instead, it will be treated as a fact.

All date formats support both one-digit and two-digit formats for a day and a month.

That is, 01-08-2014 and 1-8-2014 are interchangeable and will both work.

The following dates are supported and will work well:

The following dates are not supported and will not be accepted:

If you use a comma (,) as a delimiter, use a dot (.) as a decimal separator.
```
product_name,category,price,quantity
Shirt,Clothing,100.33,1.00
```
If you use a comma (,) as a decimal separator, use a semicolon (;), vertical bar (|), or a tab (⇥) as a delimiter.
```
product_name,category,price,quantity
Shirt;Clothing;100,33;1,00
```
If you have to use a comma (,) both as a delimiter and as a decimal separator, put decimal numbers inside double quotation marks.
```
product_name,category,price,quantity
Shirt,Clothing,"100,33","1,00"
```
