• This tool is no longer maintained. The latest release of sqlite-utils introduces a new sqlite-utils convert command which provides a super-set of the functionality provided by sqlite-transform. #11

• sqlite-transform lambda --multi option allowing the function to return a Python dictionary defining multiple columns that will be created and populated. #4
• --drop option can be used with --output or --multi to drop the original column. #15
• All commands now require at least one column to be specified. #17

New -s or --silent option for hiding the progress bar. #14

New --output colname and --output-type integer options for all of the commands, see saving the result to a separate column. #13

• --dayfirst and --yearfirst options for parsedate and parsedatetime commands. #12

• New sqlite-transform jsonsplit for converting foo,bar into ["foo", "bar"]. #10
• Added --dry-run option to sqlite-tranfsorm lambda for previewing the conversion that is about to be applied. #8

• Better --help for sqlite-transform lambda. #7

• return is now optional for one-line lambdas, e.g.

  sqlite-transform lambda my.db mytable mycolumn --code='str(value).upper()'
  

• Added lambda command, which lets you specify a Python expression (or multiple lines of code) to be executed against every value in the column. Documentation here. (#2)
• Added a parsedate command, which works like parsedatetime except it outputs just the date component. (#1)

• First release, supporting only the parsedatetime command.
