![]() I note that attempting to use the import Wizard doesn't work for CSV, Excel or XML. Confirmed: Using JRE 7 fixes the problem I'm currently using the zip-unpacked Java version of RapidMiner to analyse SurveyMonkey responses to open-ended questions, stored as spreadsheets. ![]() This gives more control especially when the input data is not clean. Resolved - Rapidminer uses JRE 7, was using JRE 6. If you can get quotes around the fields, this will help because it allows delimiter characters to appear in the field.ĭates formats can be handled using the data format parameter but my advice is to import the date field as a polynominal and then convert it later to date using the Nominal to Date operator. Note: Don’t create a custom directory for your repository in the same location where the RapidMiner Studio program is. The upgrade only affects where the RapidMiner Studio program is installed. function in the Repositories drop down list.

Do not use this if your data does not contain these because the input process will import everything into the first field. The use quotes option requires that each field is surrounded by double quotes. Choose from local, HDFS, Amazon S3, or Azure HDInsight (Blob / Data Lake) file systems. The Sample Data Size specifies the number of rows that are shown as the data sample in Steps 2 and 3. It's virtually impossible to debug this without seeing the data. My problem is that the write excel operator writes over the excel file rather. Set the Sample Data Size and identify the file system.
