Use the APSW shell: http://rogerbinns.github.io/apsw/shell.html Behind the scenes it uses the Python CSV libraries which support a number of dialects including excel (default) and excel-tab. The APSW shell also supports an .autoimport command. It automatically works out dialects, separators and data types. Here is the extended help: ==== 8< ==== sqlite> .help autoimport .autoimport FILENAME ?TABLE? Imports filename creating a table and automatically working out separators and data types (alternative to .import command) The import command requires that you precisely pre-setup the table and schema, and set the data separators (eg commas or tabs). In many cases this information can be automatically deduced from the file contents which is what this command does. There must be at least two columns and two rows. If the table is not specified then the basename of the file will be used. Additionally the type of the contents of each column is also deduced - for example if it is a number or date. Empty values are turned into nulls. Dates are normalized into YYYY-MM-DD format and DateTime are normalized into ISO8601 format to allow easy sorting and searching. 4 digit years must be used to detect dates. US (swapped day and month) versus rest of the world is also detected providing there is at least one value that resolves the ambiguity. Care is taken to ensure that columns looking like numbers are only treated as numbers if they do not have unnecessary leading zeroes or plus signs. This is to avoid treating phone numbers and similar number like strings as integers. This command can take quite some time on large files as they are effectively imported twice. The first time is to determine the format and the types for each column while the second pass actually imports the data. ==== 8< ==== Roger -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iEYEARECAAYFAlW6dDEACgkQmOOfHg372QRG5ACgt/OpLOPVZ40YQ4B2EWBf7yk0 HCUAniZLLUkPs7ac7cvCLb7Bn3zyNguC =YpCt -----END PGP SIGNATURE-----
