How to search and replace a Text String in a Word DOCX in Node.JS

By the end of today’s tutorial, you will have implemented a search and replace function for simple text strings in DOCX files. We can get this done very easily in Node.JS through use of a lovely little API designed for the task. Let’s dive into the process.

Client installation comes first:

npm install cloudmersive-convert-api-client --save

After running that command and waiting for the installation to finish, move on to calling the following function, like so:

var CloudmersiveConvertApiClient = require('cloudmersive-convert-api-client');
var defaultClient = CloudmersiveConvertApiClient.ApiClient.instance;
// Configure API key authorization: Apikey
var Apikey = defaultClient.authentications['Apikey'];
Apikey.apiKey = 'YOUR API KEY';
// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)
//Apikey.apiKeyPrefix = 'Token';
var apiInstance = new CloudmersiveConvertApiClient.EditDocumentApi();
var reqConfig = new CloudmersiveConvertApiClient.ReplaceStringRequest(); // ReplaceStringRequest | Document string replacement configuration input
var callback = function(error, data, response) {
if (error) {
console.error(error);
} else {
console.log('API called successfully. Returned data: ' + data);
}
};
apiInstance.editDocumentDocxReplace(reqConfig, callback);

Now enter in the details for your search and replace, and give it a test drive. It’s as easy as that!
