Why use PDF to JSON API?
Credits Based Payments
You do not need to buy a license to use PDF to JSON API. Instead, you can pay credits to start your conversions. You will have total security for extracting and sharing private data from your documents, with third parties.
Damaged and scanned text support
Some PDF files have scanned and damaged texts in them. Our built-in OCR (Optical Character Recognition) supports PDF files with mixed content and multiple languages.
API and Business Automation Platforms Integrations
Software developers can use PDF.co API platform from the following programming languages: PHP, Javascript, Java, C#, .NET and ASP.NET, Visual Basic, and others.
For non-developers, the PDF operations can be performed through RPA platforms such as Integromat, Zapier, UiPath, BluePrism, Automation Anywhere, and others.
On-Prem and Private Instances for Enterprise
PDF.co API uses secure and certified cloud infrastructure, however, Enterprise customers who need to process ultra-sensitive data in-house can opt for the on-premise version. It will be on your server working completely offline when required.
PDF to JSON API Sample & Demo
For this demo, I am going to use a Sample PDF File.
We’ll be using the code snippets below which are written in different programming languages which will convert the Sample PDF File above into JSON. The final result will look like this.
{
"document": {
"pageCount": "1",
"pageCountWithOCRPerformed": "0",
"page": {
"index": "0",
"OCRWasPerformed": "False",
"row": {
"column": {
"text": {
"fontName": "Arial",
"fontSize": "24.0",
"fontStyle": "Bold",
"color": "#0000EF",
"x": "72.10",
"y": "70.60",
"width": "140.74",
"height": "24.00",
"text": "Hello World!"
}
}
}
}
}
}
Output JSON
Before we proceed with the code. Let us first check the /v1/pdf/convert/to/json parameters and its uses.
Endpoint
| URL: | https://api.pdf.co/v1/pdf/convert/to/json2 |
| Method: | POST |
| Parameter | Description |
| url | required. Link to the source file. |
| lang | optional. english by default. Sets OCR (image to text extraction) language to be used for scanned PDF when a scanned document is detected or input is PNG, JPG images. Other supported values: eng, spa, deu, fra, jpn, chi_sim, chi_tra, kor. You can also specify two languages to be used on the same page, for example: eng+deu, jpn+kor or other combinations. |
| inline | optional. Must be one of: true to return data as inline or false to return link to the output file (default). |
| unwrap | optional. Unwrap lines to a single line within table cells when lineGrouping is enabled. Must be one of true or false. |
| pages | optional. Comma-separated list of page indices (or ranges) to process. IMPORTANT: the very first page starts with 0 (zero). To set a range use the dash –, for example: 0, 2-5, 7-. |
| rect | optional. Defines coordinates for extraction, e.g. 51.8, 114.8, 235.5, 204.0. Must be a string. |
| encrypt | optional. Enable encryption for the output file: true or false |
| async | optional. Runs processing asynchronously. Returns jobId to use with job/check: true or false |
| name | optional. Output file name. |
| profiles | optional. Must be a String. Set custom configuration. See profiles examples here |
| lineGrouping | optional. Line grouping with table cells. Set to 1 to enable the grouping. Must be a string. |
Now we are ready to write some codes.
