Hi Ramesh,

just a note to above comment; I haven't tried for files larger than 18/19MB.

Possibly there is some limit of 20MB you can get to know that since ServiceNow internally has limit how much string value a variable can hold

Nope you cannot use similar approach to combine 2 pdf files;

check below links:

Thanks for the links. Am completed with converting 4 files to base64 which all are around 12MB, now am placing in json format but am not getting final json format.

var gliObj = new GlideRecord('sys_attachment');
gliObj.addQuery('table_name', 'dms_document_revision');
gliObj.addQuery('table_sys_id', '405a9589db764890d17be1c2ca96197a');
gliObj.query();
var reqObj = {};
var reqArr = [];
while (gliObj._next()) {
var StringUtil = new GlideStringUtil();
var gsis = GlideSysAttachmentInputStream(gliObj.sys_id.toString());
var ba = new Packages.java.io.ByteArrayOutputStream();
gsis.writeTo(ba, 0, 0);
ba.close();
var base64EncodedData = StringUtil.base64Encode(ba.toByteArray());
var obj = {};
obj.docName = "doc.pdf";
obj.format = base64EncodedData;
reqArr.push(obj);
}
gs.info('xresp:executed'+reqArr);
reqObj.objPdf = reqArr;

gs.info('final json format:' + JSON.stringify(reqObj));

am unable to get the final json format. Please advice.

Hi Ramesh,

possibly because the json string is long enough hence it is not printing

am getting below error:

"Javascript compiler exception: String object would exceed maximum permitted size of 33554432".

can we increase the size limit or

Is there any other way to get the final json.?
