CSV-formatted files, generated by Excel or other office tools, can be uploaded to frePPLe. Clicking on the import arrow in the upper right corner allows you to select a the file to upload.
The first line in the file should contain the field names (not case sensitive). To get a sample of the input format, you can first create a CSV export: the CSV export and import formats are identical.
Optionally, you can choose to delete the existing contents of the table before uploading the new data. When the option is selected, dependent tables are also erased: e.g. if you erase the resource table, also the load table will be erased since the second table references the first one.

After the upload, a message on the screen will report the data errors found. The total number of records that was added or changed is also shown.

You need add-permission on the entity to be able to import CSV-data files. And you need delete-permission to use the extra erase option.
An appropriate message is shown when you don’t have these permissions.
Note that the separator in the CSV-files varies with the chosen language: If in your language a comma is used as a decimal separator for numbers, the CSV file will use a semicolon (;) as delimiter. Otherwise a comma (,) is used. See http://en.wikipedia.org/wiki/Decimal_mark
The import process will scan the Unicode BOM header of the import file. If a header is detected the appropriate unicode character encoding is used. If no header is used frePPLe assumes the data is encoded in the character set defined by the setting CSV_CHARSET (default = UTF-8).
Since Excel is saving a CSV file in the default Windows code page of your system, you might want to update this setting CSV_CHARSET to match your system. This will ensure a smoother integration.
