Either click the plus sign (+) or drag your file(s) for upload. If you are uploading multiple files, the column names and data types must match. OmniSci supports only delimiter-separated formats such as CSV and TSV. OmniSci supports Latin-1 ASCII format and UTF-8. If you want to load data with another encoding (for example, UTF-16), convert the data to UTF-8 before loading it to OmniSci. In addition to CSV, TSV, and TXT files, you can import compressed delimited files in TAR, ZIP, 7-ZIP, RAR, GZIP, BZIP2, or TGZ format.
