Merge and download documents

Merge and Download Documents in Zoho Writer

Description

The zoho.writer.mergeAndDownload task supplies values to the merge fields inserted to a document, and returns the new merged documents converted into a single file of specified format. The values of the merge fields are provided from a data source of type CSV or JSON.

This integration task is based on the Zoho Writer API - Merge document.

Note:
  • The merge fields inserted into the document should be the column headers of a CSV data source, or the keys in a JSON data source.
  • On average, it takes about a minute to index a file/folder after it is created or updated. This indexing time can increase if the queue size increases.  You will not get the expected result if you execute zoho.writer.mergeAndDownload task before the document you need to merge is indexed.

Syntax

<response> = zoho.writer.mergeAndDownload(<document_id>, <output_format>, <values_map>, <connection>);
where:
ParamsData typeDescription

<response>

FILE

The output file object that contains the new merged documents.

<document_id>

TEXT

The ID of the source document that will be merged with values.

The document ID can be obtained from the URL of the source document. The URL is in the following format:
https://writer.zoho.com/writer/open/<document_id>

<output_format>

TEXT

The format of the output file.

Allowed values:

  • pdf
  • docx

<values_map>

KEY-VALUE

The values that will be supplied to the merge fields. The values can be fetched only from CSV file or JSON file/text.

Note: The keys of this parameter should be specified as given in the Zoho Writer API. Applicable keys and values for CSV and JSON data as specified in Zoho Writer - Merge document API:

CSV:

  • Specify the file URL
    key: merge_data_csv_url
    value: The TEXT that represents the URL of the CSV file.
  • Specify values stored in a file object 
    key: merge_data_csv_content
    value: The FILE that contains the merge values.

JSON:

  • Specify the file URL
    key: merge_data_json_url
    value: The TEXT that represents the URL of the JSON file.
  • Specify values stored in a file object 
    key: merge_data_csv_content
    value: The FILE that contains the merge values.
  • Specify the text directly
    key: merge_data
    value: The TEXT/ KEY-VALUE that represents the JSON value. The key for the JSON value needs to be "data".

<connection>

TEXT

The link name of the connection.

Note:

  • In view of stopping new authtoken generation, a Zoho OAuth connection with appropriate scopes is mandatory in order for new integration tasks (created after the deadline specified in the post) to work as expected. Existing integration tasks will continue to work with or without the connections parameter until you manually delete the authtoken from accounts.
  • Add relevant scopes mentioned in Zoho Writer API while creating the connection.
  • Refer to this post for the list of Zoho services that support the connections page.

Example 1: Supply CSV content to the merge fields and download the new merged documents in .pdf format

The following script supplies the CSV data stored in the FILE variable - csv_content to the merge fields present in the specified documents, and stores the file to the variable - response in .pdf format.

 // Fetch the CSV data from the web and store it in the variable - csv_content
 csv_content =  invokeurl 
 [
 url : "http://insight.dev.schoolwires.com/HelpAssets/C2Assets/C2Files/C2ImportCalEventSample.csv"
 type : GET
 ];
 
 
 // Construct a KEY-VALUE variable to hold the merge data
 merge_values = Map();
 merge_values.put("merge_data_csv_content", csv_content);
 
 
 // Perform the Merge and Download task
 response = zoho.writer.mergeAndDownload("al296XXXXXXXXXXXXXXXXXXXXXXXXXXXa516c", "pdf", merge_values, "writer_oauth_connection");

where:

response
The FILE response that represents the output file object.
"al296XXXXXXXXXXXXXXXXXXXXXXXXXXXa516c"
The TEXT that represents the document ID of the source document.
"pdf"
The TEXT that represents the format of the output file.
merge_value
The KEY-VALUE variable that holds the merge data.
"writer_oauth_connection"

Example 2: Supply CSV data from a URL to the merge fields and download the new merged documents in .docx format

The following script supplies CSV values fetched from the specified URL to the merge fields present in the specified documents, and stores the file in the variable - response.

 // Construct a KEY-VALUE variable to hold the merge data and subject of the email
 merge_values = Map();
 merge_values.put("merge_data_csv_url", "http://insight.dev.schoolwires.com/HelpAssets/C2Assets/C2Files/C2ImportCalEventSample.csv");
 
 
 // Perform the Merge and Download task 
 response = zoho.writer.mergeAndDownload("al296XXXXXXXXXXXXXXXXXXXXXXXXXXXa516c", "docx", merge_values, "writer_oauth_connection");

where:

"docx"
The TEXT that represents the format of the output file.
"merge_data_csv_url"

Example 3: Supply JSON content in TEXT format to the merge fields and protect the downloaded .docx file with a password

The following script supplies JSON values held by the variable - json_text to their respective merge fields, and protects the downloaded .docx file with the password - mergedFile2019.

 // Assign the JSON data in TEXT format to the variable - json_text
 json_text = "{\"data\":[{\"Name\":\"Shawn\",\"Age\":\"20\"},{\"Name\":\"Kate\",\"Age\":\"29\"}]}";
 
 
 // Construct a KEY-VALUE variable to hold the merge data
 merge_values = Map();
 merge_values.put("password", "mergedFile2019");
 merge_values.put("merge_data", json_text);
 
 
 // Perform the Merge and Download task 
 response = zoho.writer.mergeAndDownload("al296XXXXXXXXXXXXXXXXXXXXXXXXXXXa516c", "docx", merge_values, "writer_oauth_connection");
