 For example, to download a CSV file with CPU utilization of the last hour,
 [click here](https://registry.my-netdata.io/api/v1/data?chart=system.cpu&after=-3600&format=csv&options=nonzero&tqx=outFileName:system+cpu+utilization+of+the+last_hour.csv).

 The CSV formatter presents [results of database queries](../../queries) in the following formats:
 
-format|content type|description
-:---:|:---:|:-----
-`csv`|text/plain|a text table, comma separated, with a header line (dimension names) and `\r\n` at the end of the lines
-`csvjsonarray`|application/json|a JSON array, with each row as another array (the first row has the dimension names)
-`tsv`|text/plain|like `csv` but TAB is used instead of comma to separate values (MS Excel flavor)
-`html`|text/html|an html table
-`markdown`|text/plain|markdown table

 In all formats the date and time is the first column.
 
 The CSV formatter respects the following API `&options=`:
 
-option|supported|description
-:---:|:---:|:---
-`nonzero`|yes|to return only the dimensions that have at least a non-zero value
-`flip`|yes|to return the rows older to newer (the default is newer to older)
-`seconds`|yes|to return the date and time in unix timestamp
-`ms`|yes|to return the date and time in unit timestamp as milliseconds
-`percent`|yes|to replace all values with their percentage over the row total
-`abs`|yes|to turn all values positive
-`null2zero`|yes|to replace gaps with zeros (the default prints the string `null`

 Instead it is used by the [`ssv`](../ssv) formatter
 and [health monitoring queries](../../../../health).
