How to Convert XLSX to HTML with Our API
You can convert your XLSX or XLS files to HTML using our API in three simple steps, as outlined below. The only thing to watch out for is the file size limit. The files you convert should be less than 2GB.
Step 1: Get Upload Link
You need an upload link to send your XLSX file to our API for conversion. To get the upload link, you can call “/file/upload/get-presigned-url” method. The API will return the upload link “presignedUrl” and the access link “URL”.
Step 2: Upload File to XLSX to HTML API
You can now upload your Excel or Open sheet file for conversion to HTML. To do that, use the “PUT” method to send the XLS/XLSX file to “presignedUrl”. Moreover, you have to send it within 30 minutes after you get the upload link.
Step 3: Execute XLSX to HTML API
Once your file is uploaded, you can now call the /xls/convert/to/html or /xlsx/convert/to/html methods, by including the access “URL” and your API access key. Your files will be converted and made available for download within 25 seconds.
How to Run XLS/XLSX to HTML API Asynchronously
You will get a time-out error after 25 seconds if you attempt to convert a large XLS/XLSX file synchronously. The solution is to run the execution asynchronously and in the background. To do that, you must set the “async” input param to “true”.
The API will immediately create a background job, and return a unique “jobId” property, and an output “URL”. You can use the “jobId” to check the status of the task, and the “URL” to access the file, once the conversion is complete.
To check the execution status of the job, you can use the “/job/check” method and then wait for it to output a “success” status. Once you get a success status, you can download the HTML file from the “URL”.
