This tool uses Sentistrength to analyze the sentiment of short texts. Three types of data can be uploaded: Netvizz, DMI-TCAT, or a regular CSV file.

NetVizz data

Go to Netvizz and download a data file in tabular format (e.g. liked pages with comments) for input in this tool

DMI-TCAT

Go to DMI-TCAT and do a 'Full Export' for your data set for input in this tool.

Other text data

You can also upload a tab separated CSV file, with a single header line. Text in the left most column of the CSV file will be analysed using Sentistrength.

To save a spreadsheet as a tab separated CSV file, in the free Libre Office do the following: File > save as > csv (check edit filter settings) > field delimiter: {tab} > save. All other settings are default.
