## TL;DR

The text is longer than the field allows. Truncate it, split it across fields, or move it to a long-text field.

## Error

```text
TEXTAREA_VALUE_TOO_LONG
```

## Steps

1. Check the field's max length Expected: you know the limit.
2. Truncate the value or move it to a long text area field Expected: it fits.
3. Re-run the operation Expected: it succeeds.
4. Truncate programmatically before sending Expected: it cannot regress.

## When to use

- TEXTAREA_VALUE_TOO_LONG
- Text exceeds the field length

## When not to use

- The text looks short (then count: multibyte characters can count more)
- You need the full text (then use a long text area or files)

## Tool compatibility

- Salesforce text field limits
- Data imports

## Variant phrasings

### textarea value too long

Truncate to the field's max length or use a long-text field.

### TEXTAREA_VALUE_TOO_LONG

Same: the value does not fit.

## Why it happens

Source systems have longer fields than Salesforce. Agents copy verbatim and the tail gets rejected.

## Edge cases

- Rich text fields count HTML tags toward the limit
- Truncation can break multi-byte characters; truncate on character boundaries
