如何使用 Google App Script 将格式化文本从 google sheet 单元格保存到 .rtf？

Question

I have a simple script in Google App Script, which takes string-values from cells in a google sheet (RSS-Feeds) and saves (updates) some.rtf - Documents. After some sync-processes and macro-helpers, those texts are displayed on a scrolling LED-bar, which can be updated through WIFI.

This works but I didn't manage to format the texts in the.rtf - Documents.

I experimented with the RichTextValueBuilder, which works fine to add formatting to text in a google spreadsheet but wasn't successful for formatting text in the.rtf's... Another experiment was with html-tags. This brought the desired formatting-effect in the rtf-file but the application for the led-bar couldn't handle it.

Does anybody know how to help a noob in this situation? Thanks a lot in advance!

 function dataLED() { var ss = SpreadsheetApp.getActiveSpreadsheet(); var ass = ss.getSheetByName("Newsticker"); //VALUES FROM CELLS IN GOOGLE SHEETS var valuesLedBar = ass.getRange(2, 10, 4, 1).getValues(); var vak1 = valuesLedBar[0]; var vak2 = valuesLedBar[1]; var vak3 = valuesLedBar[2]; var vak4 = valuesLedBar[3]; var marge = ass.getRange("B16").getValue(); //SAVE IN.RTF-FILES (IN FOLDER dataLEDbar) var folders = DriveApp.getFoldersByName("dataLEDbar"); if (folders.hasNext()) { var folder = folders.next(); saveData(folder, "0808003135589.rtf", vak1); saveData(folder, "0808003133343.rtf", vak2); saveData(folder, "0808003136619.rtf", vak3); saveData(folder, "0808003135964.rtf", vak4); saveData(folder, "0808182631849.rtf", "Gewinnmarge diesen Monat:" + marge); } else {null} }; //-------------------------------------------------SAVE function saveData(folder, fileName, contents) { var children = folder.getFilesByName(fileName); var file = null; if (children.hasNext()) { file = children.next(); file.setContent(contents); } else { file = folder.createFile(fileName, contents); } }

Here is my understanding:

• You have a Google Spreadsheet which has the rich text in the cells of "J2:J5".
• You want to retrieve the rich texts from the cells of "J2:J5", and want to create them as each file with the mimeType of application/rtf .
  • In your case, 4 rich text files are created.
• You want to achieve this using Google Apps Script.

In this answer, in order to achieve your goal, I used a Google Apps Script library of RichTextApp .

Usage:

1. Install GAS library.

Please install the GAS library of RichTextApp. You can see how to install at here .

2. Sample script.

Please copy and paste the following sample script, and run myFunction . By this, when the folder is existing, 4 rich text files are created to the folder.

function myFunction() {
  const filenames = ["0808003135589.rtf", "0808003133343.rtf", "0808003136619.rtf", "0808003135964.rtf"];
  const folderName = "dataLEDbar";
  const sheetName = "Newsticker";

  const folders = DriveApp.getFoldersByName(folderName);
  const folder = folders.hasNext() ? folders.next() : DriveApp.getRootFolder();
  const ss = SpreadsheetApp.getActiveSpreadsheet();
  const sheet = ss.getSheetByName(sheetName);
  for (let i = 2; i <= 5; i++) {
    const range = sheet.getRange("J" + i);
    const doc = DocumentApp.create("tempDocument");
    const docId = doc.getId();
    RichTextApp.SpreadsheetToDocument({range: range, document: doc});
    doc.saveAndClose();
    const url = "https://docs.google.com/feeds/download/documents/export/Export?exportFormat=rtf&id=" + docId;
    const res = UrlFetchApp.fetch(url, {headers: {authorization: "Bearer " + ScriptApp.getOAuthToken()}});
    folder.createFile(res.getBlob().setName(filenames[i - 2]));
    DriveApp.getFileById(docId).setTrashed(true);
  }
}

Note:

• This is a simple sample script. So please modify this for your actual situation.

Not sure, if this is helping anybody but I found a possible workaround for the problem. Better solutions are welcome, as this looks ugly and will not work in every case...

The RTF-file is formatted beforehand and I just append the text from the google sheet instead of replacing the content and formatting of the RTF.

function appendText() {

//Search Params for File and Folder
var fileName = "testRtf.rtf";
var folderName = "dataLEDbar";
//New Text in .rtf
var content = "NEWTEXT";

// get list of folders with matching name
var folderList = DriveApp.getFoldersByName(folderName);
if (folderList.hasNext()) {
    //folder
    var folder = folderList.next();

    // search for files with matching name
    var fileList = folder.getFilesByName(fileName);

    if (fileList.hasNext()) {
        //file
        var file = fileList.next();

        //get rtf-file as string from Blob      
        var rtfContent = file.getBlob().getDataAsString();
        //split Blob 
        var splitBlob = rtfContent.split("\\");
        var lenSplitBlob = splitBlob.length;
        //and replace last array with new text
        splitBlob[lenSplitBlob - 1] = "cf2 " + content + "}";

        //new Blob
        var newBlob = splitBlob.toString().replace(/,/g, '\\');

        //append text to already formatted .rtf-File
        file.setContent(newBlob);

    } else {
        // file not found
        null
    }
}

}
