These processes are essential for any macro development. + +![LibreOffice Calc Macro - Join Data][1] + +Let’s put three strings like below in a LibreOffice calc sheet and join them. + +### Joining Strings in Calc + +In basic, to join two strings/texts, use the “&” operator. We will use this to join three columns of strings and put the results in another column. + +``` +Sub String_join() + part1 = ThisComponent.Sheets(0).getCellByPosition(0,1) + part2 = ThisComponent.Sheets(0).getCellByPosition(1,1) + part3 = ThisComponent.Sheets(0).getCellByPosition(2,1) + + result_cell = ThisComponent.Sheets(0).getCellByPosition(3,1) + result_cell.String = part1.String & "." & part2.String & "." & part3.String +End Sub +``` + +![LibreOffice Calc Macro – Join][2] + +Let’s put some more strings in Column A as below in LibreOffice. We will use these three strings for the rest of the processing in this tutorial. + +### Left + +The `left` function returns the number of characters from a string from the left side. The number of characters can be specified in the argument of the function. Put a string in cell A1 – “www.google.com” and run the function on the A1 cell as below. This function will return sub-string “www”. + +``` +Sub left_demo() + part1 = ThisComponent.Sheets(0).getCellByPosition(0,0) + result = ThisComponent.Sheets(0).getCellByPosition(2,0) + result.String = left(part1.String,3) +End Sub +``` + +![LibreOffice Calc Macro – Left Example][3] + +### Right + +Just like the `left` function above, the `right` returns the given no of characters from the right side. With the same example, in this case, the below function would return “com”. + +``` +Sub right_demo() + part1 = ThisComponent.Sheets(0).getCellByPosition(0,0) + result = ThisComponent.Sheets(0).getCellByPosition(2,0) + result.String = right(part1.String,3) +End Sub +``` + +![LibreOffice Calc Macro – Right Example][4] + +### Mid + +The `mid` function returns any size of the sub-string from a given string. The argument of this function is `Mid(string, start position, length of the sub-string)`. To have the Mid function work, put some strings in a column in LibreOffice calc and run the Mid function. + +In this example below, the strings from A columns are converted to sub-string in column B. The sub-string starts from character 4 of the string, and the length is six characters. + +``` +Sub mid_demo() + part1 = ThisComponent.Sheets(0).getCellByPosition(0,1) + result = ThisComponent.Sheets(0).getCellByPosition(1,1) + result.String = mid(part1.String,5,6) + + part2 = ThisComponent.Sheets(0).getCellByPosition(0,2) + result = ThisComponent.Sheets(0).getCellByPosition(1,2) + result.String= mid(part2.String,5,6) + + part3 = ThisComponent.Sheets(0).getCellByPosition(0,3) + result = ThisComponent.Sheets(0).getCellByPosition(1,3) + result.String = mid(part3.String,5,6) +End Sub +``` + +![LibreOffice Calc Macro – Mid Example][5] + +### Trim + +The trim function is used to remove leading and trailing spaces from a string.The function can be used like this: `Trim(your_string_here)` + +### Len + +Len function returns the number of characters present, i.e. the length of a string.Usage: `Len(string)` + +### Instr + +The `Instr` function is used to search a string within a string. If a match is found, Instr returns the starting position number of the searched string, and if not found, it returns 0. + +``` +Sub instr_demo() + part1 = ThisComponent.Sheets(0).getCellByPosition(0,1) + result = ThisComponent.Sheets(0).getCellByPosition(1,1) + result.Value = instr(part1.String,"oogl") + + part2 = ThisComponent.Sheets(0).getCellByPosition(0,2) + result = ThisComponent.Sheets(0).getCellByPosition(1,2) + result.Value = instr(part2.String,"dd") + + part3 = ThisComponent.Sheets(0).getCellByPosition(0,3) + result = ThisComponent.Sheets(0).getCellByPosition(1,3) + result.Value = instr(part3.String,"untu") +End Sub +``` + +![LibreOffice Calc Macro – Instr Example][6] + +In this tutorial, basic string processing is covered, which can be used in LibreOffice Macro. + +### Looking for Something Else? + +If you are looking for something else in LibreOffice macro tutorials, Or want to learn more about it, please follow the below link for the complete Macro Tutorials Index: + +[LibreOffice Macro Tutorial Index][7] + +-------------------------------------------------------------------------------- + +via: https://www.debugpoint.com/string-processing-in-libreoffice-calc-macro-with-examples/ + +作者：[Arindam][a] +选题：[lkxed][b] +译者：[译者ID](https://github.com/译者ID) +校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 + +[a]: https://www.debugpoint.com/author/admin1/ +[b]: https://github.com/lkxed +[1]: https://www.debugpoint.com/wp-content/uploads/2014/11/LibreOffice-Calc-Macro-Join-Data.png +[2]: https://www.debugpoint.com/wp-content/uploads/2014/11/LibreOffice-Calc-Macro-Join.png +[3]: https://www.debugpoint.com/wp-content/uploads/2014/11/LibreOffice-Calc-Macro-Left-Example.png +[4]: https://www.debugpoint.com/wp-content/uploads/2014/11/LibreOffice-Calc-Macro-Right-Example.jpg +[5]: https://www.debugpoint.com/wp-content/uploads/2014/11/LibreOffice-Calc-Macro-Mid-Example.png +[6]: https://www.debugpoint.com/wp-content/uploads/2014/11/LibreOffice-Calc-Macro-Instr-Example.png +[7]: http://www.debugpoint.com/libreoffice-basic-macro-tutorial-index/ +[8]: https://www.debugpoint.com/enable-rpm-fusion-fedora-rhel-centos/ +[9]: https://news.google.com/publications/CAAqBwgKMOCfmgsw-qmyAw +[10]: https://t.me/debugpoint
