Our verdict
Form ITC-01 is the declaration a business files to claim input tax credit on stock it already holds — for example when it newly becomes liable to register or moves out of the composition scheme. When the stock list runs to hundreds of lines, this offline Excel tool is easier than typing on the portal: fill it in, generate the JSON and upload it after logging in. Version 1.3 is on gst.gov.in with a SHA-256 hash to check.
