Repair Excel Files

This REST API allows you to repair Excel files.

Repair XLS, XLSX, XLSM, XLSB, ODS and other spreadsheet formats.
Supports uploading multiple files in a single request.

Aspose.Cells Cloud Excel Repair recovers data from corrupt Excel files online without any installation. Corrupted Excel files are problematic because they cannot be opened. You can try the Aspose.Cells Cloud Excel Repair app to recover data from such files.

REST API

The Repair Excel Files endpoint repairs corrupted spreadsheet files and returns the repaired content.

Prerequisites – You must obtain a JWT access token from Aspose Cloud (OAuth 2.0 client‑credentials flow) before invoking the API.

Authentication – Include the token in the request header:

Authorization: Bearer <access_token>

POST https://api.aspose.cloud/v3.0/cells/repair

The request parameters are:

Parameter Name	Type	Location	Description
file	file	formData (multipart)	File to upload
format	string	query	Desired output format. If omitted (null), the output format defaults to the same format as the input file.

The OpenAPI Specification defines a publicly accessible programming interface and lets you carry out REST interactions directly from a web browser.

You can use the cURL command‑line tool to access Aspose.Cells web services easily. The following example shows how to make calls to the Cloud API with cURL.
